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
rovers,United and City are football teams
rovers scored x goals
United scored 8 goals more than rovers
City scored 3 goals less than twice the number of goals scored by rovers
the three teams scored a total of 117 goals
solve to find the value of x
Based on the information given, the value of x is 28 which means that Rovers scored 28 goals.
Number of goals scored by Rovers = x
United scored 8 goals more than rovers. This will be = x + 8
City scored 3 goals less than twice the number of goals scored by rovers. This will be: = 2[x} - 3 = 2x - 3
Since the three teams scored a total of 117 goals, this will be:
x + x + 8 + 2x - 3 = 117
Collect like terms
4x = 117 - 8 + 3
4x = 112
x = 112/4
x = 28
The value of x is 28

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

Hey there! I'm happy to help!
The equation y=0.5x simply means that Joseph is hiking 0.5 miles every hour. This is because the x value is the independent variable or the thing you change, which in this case is the time you take hiking. The distance, the y-value, is dependent on that time.
Now, let's look at Kelly's graph. This graph isn't a grid, so we will have to eyeball some of the numbers on the graph. It appears that after 10 hours, Kelly has traveled eight miles. This is because if you go up from the 10 and meet the line and then go to the left. you will be about at the line right below the 10 on the y-axis, and if you count the lines, you will see that we are counting by 2, so it has to be eight.
So, we see that Kelly takes 10 hours to go eight miles. We know that Joseph's distance is half of his time (4 hours would be 2 miles, 6 hours would be 3 hours, etc.)
So, if we say that Joseph hikes for ten hours, he will have hiked five miles as that is half of ten. We see, though, that Kelly made it eight hours in that time, so Kelly is going faster here.

Question: If a point C is inside AVB then m AVC +_______= m AVB
m∠AVC+m∠CVB=m∠AVB. Option b is correct.
Given a figure in which point C is inside ∠AVB and ∠AVB=62°.
A geometric figure formed by two lines starting from a common point or two planes starting from a common line is called an angle. The space between these lines or planes is measured in degrees.
Knowing that a point C is between ∠AVB and ∠AVC=39° and ∠CVB=23°, then
From the figure, we can see that C is inside ∠AVB, so ∠AVB is divided into two parts, namely ∠AVC and ∠CVB
m∠AVC+m∠CVB=m∠AVB
Now substitute the values we get
39°+23°=62°
62°=62°
So both sides are equal and it's proven.
Hence, a point C is between ∠AVB and ∠AVB=62° then m∠AVC+m∠CVB=m∠AVB.

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.
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.

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
