Pls help me :) I would appreciate it
Step-by-step explanation:
you are just using the number after the ; and switching it for the varible and seeing if the function is true or false (points :p)
X= (2a+5)² Y= (a-3)²
X+Y??
Answer:
X = (2a + 5)^2 = 4a^2 + 20a + 25
Y = (a-3)^2 = a^2 - 6a + 9
4a^2 + 20a + 25 + a^2 - 6a + 9
X + Y = 5a^2 + 14a + 34

A rectangle has an area of 21 square centimeters. Which of the following could be the rectangle's length and width? Area = length x width Choose all answers that apply
2(x-1)(x+2)[tex]2(x-1)(x+2)[/tex]
[tex]\boxed{\underline{\bf \: ANSWER}}[/tex]
I assume the following equation is the question you asked.
[tex] \rightarrow \sf \: 2(x - 1)(x + 2)[/tex]
If yes, these are the following are the steps to reach your answer :-
[tex]\sf \: 2(x - 1)(x + 2)[/tex]
Use the distributive property to multiply 2 by x - 1.
[tex] \sf \: \left(2x-2\right)\left(x+2\right) [/tex]
Apply the distributive property by multiplying each term of 2x - 2 by each term of x + 2.
[tex] \sf \: 2x^{2}+4x-2x-4 [/tex]
Combine 4x and - 2x to get 2x.
[tex] \boxed{ \bf \: 2x^{2}+2x-4 }[/tex]
=> The answer will be 2x² + 2x - 4.

Which number would divide the numerator and the denominator of the first fraction to yield the second fraction?
A) 5/5
B) 12/12
C) 15/15
D) 4/4
E) 3/3
Answer:
E) 3/3
Step-by-step explanation:
12/15 ÷ X = 4/5
We need to divide the top and bottom by 3/3
12 ÷3 =4
15÷3 = 5
5) What is the result of subtracting (x2 + 3x)from the polynomial (-2x2 + 4x + 5)?
Answer:
- 3x² + x + 5
Step-by-step explanation:
- 2x² + 4x + 5 - (x² + 3x) ← distribute by - 1
= - 2x² + 4x + 5 - x² - 3x ← collect like terms
= - 3x² + x + 5
Hi
Golden rule to know by heart : you can only add or substract element of the same kind.
so X^2 with X^2 , X with X , numbers with numbers...
exemple : 2X^2 +3X^2 = 5X^2
but 5X^2 -3X remains that way as 5X^2 is a " X^2" and " 3X" is a " X" so I can't substract two elements of different kind.
Now you have to translate what is ask of you into a calculus.
so : you have
A ) ( 2x^2+4x +5) - ( x^2+3x)
Math is a sport of the mind. You will only progress and become stronger if you train.
So I let you have a shot. beware of signs rules. If you still have trouble, ask in comment section..
Out of 65 students, 35 like lays, 24 likes kurkure and 15 is do not like any of them,present the above information in a venn-diagram and find the number of a students who like
both the items.
Step-by-step explanation:
n(U) = 65
n(L) = 35
n(K) = 24
n(LUK) = 15
n(LnK) = x
Since we don't know the intersection (x), we have not also known the real value of Set L and K. Therefore, it is expressed as:
35-x and 24-x
Add the terms together and equate to the universal set :
35-x + x + 24-x + 15 = 65
35 + 24 + 15 + x-x - x = 65
74 - x = 65
- x = 65 - 75
-x = - 9
divide through by -1, you'll get:
x = 9
Therefore, the number of students who like both is 9.

Which of theese have a algebrac expression for "some number to the power of 5"
5^x
x^5
5x
x+5
Answer:
it's
x^5
Step-by-step explanation:
because the number is x and the power of 5 is the little number that goes to the top right of x
Given that measure angle AEB equals 4x+1 and measure angle CED equals 3x, determine the missing measures.
[tex]\\ \rm{:}\dashrightarrow 4x+1=3x[/tex]
[tex]\\ \rm{:}\dashrightarrow 4x-3x=1[/tex]
[tex]\\ \rm{:}\dashrightarrow x=1[/tex]
Now
[tex]\\ \rm{:}\dashrightarrow 3x=3(1)=3[/tex]
[tex]\\ \rm{:}\dashrightarrow 4x+1=4(1)+1=5[/tex]
Answer:
AEB = -3
CED = -3
Step-by-step explanation:
We can make an equation and solve for x.
4x + 1 = 3x
~Subtract 1 to both sides
4x = 3x - 1
~Subtract 3x to both sides
x = -1
Now we can substitute that value of x into both angles.
4(-1) + 1 = -4 + 1 = -3
3(-1) = -3

The population of the city is 5040000 and the rate of growth is 2.5℅ per annum. Find the population After one year.
Answer:
5,166,000
Step-by-step explanation:
grown population after 1 year=2.5/100×5040000
which is 126,000
total population after 1year=5040000+126000
which is 5166000
Find the midpoint between 3pi and pi
Explanation:
We apply the midpoint formula like so
C = (A+B)/2
C = (3pi+pi)/2
C = (4pi)/2
C = 2pi
This means 2pi is exactly halfway between pi and 3pi
This is similar to saying that 2 is halfway between 1 and 3. Think of the "pi" as "1pi", and we're effectively just looking at the coefficients.
CAN SOMONE PLEASE HELP.
a coin is weighed so the probability of landing head is 0.6. If this coin is flipped teice find the experimatal probabillaty of getting two heads.Anwser as a percent
hi <3
simply multiply the probabilities together:
0.6 x 0.6 = 0.36
multiply by 100 to turn this into a percentage:
0.36 x 100 = 36
thus, your answer is 36%
hope this helps :)

4. Your first six-month auto insurance premium was $729.00. Based on your good
driving record, your renewal premium is $648.81. What percent decrease did you see
in your premium? (2 points)
I
Answer: 11%
Step-by-step explanation:
729-648.81=80.10
What percent is 80.10 of 729
%/100 = is/of (this may help you)
X/100 = 80.10/729 (cross multiplication)
(80.19*100)/729 =

Which ordered pair is a solution of the system of equations? y= 3x + 1 y= 5x - 1 A (2,3) © (1,2) B (0, 1) D (1,4)
Answer:
D
Step-by-step explanation:
So first, we have to test the pairs. Let start with equation 1.
7=\=3 x
4=\=2 x
0=0 ✓
4=4 ✓
Now we only have to test B and D.
0=\=-1
4=4 ✓
D is the correct answer.
Rotate ΔCAR if C(-1,-4), A(2,3), R(-3,-2) 180° about the origin
Answer:
C(1,4) , A(-2,-3), R (3,2)
Step-by-step explanation:
the formula thing for rotating 180° about the origin is (x,y) -> (-x,-y)
this doesn't mean make the number negative, but make it the opposite if that makes sense
e.g. F(2,-4) -> F(-2,4)

Quick I need help I’ll mark u as brain list
Answer:
4
Step-by-step explanation:
The sum of three consecutive integers is 165 what are the integers
Answer:
54, 55, 56
Step-by-step explanation:
The first integer is x
so the second is x + 1
and the third is x + 2
Add all these together:
so (x) + (x+1) + (x+2) = 165
Group:
x + x + x + 1 + 2 = 165
Combine like terms:
3x + 3 = 165
3x = 162
x = 54
So the first integer is 54
The second is x + 1 = 54 + 1 = 55
And the third is x + 2 = 54 + 2 = 56
54 + 55 + 56 = 165
Answer:
54,55,56
Step-by-step explanation:
Let the three consecutive integers be x,x+1,x+2
x+x+1+x+2=165
or, 3x+3=165
or, 3x=165-3
or, 3x=162
or, x=162/3
or, x=54
Now,
x+1=54+1=55
x+2=54+2=56
