Find the value of X
Step-by-step explanation:
Equation at the end of step 1
(3x2 - 38x) + 24 = 0
STEP2:Trying to factor by splitting the middle term
2.1 Factoring 3x2-38x+24
The first term is, 3x2 its coefficient is 3 .
The middle term is, -38x its coefficient is -38 .
The last term, "the constant", is +24
Step-1 : Multiply the coefficient of the first term by the constant 3 • 24 = 72
Step-2 : Find two factors of 72 whose sum equals the coefficient of the middle term, which is -38 .
-72 + -1 = -73 -36 + -2 = -38 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -36 and -2
3x2 - 36x - 2x - 24
Step-4 : Add up the first 2 terms, pulling out like factors :
3x • (x-12)
Add up the last 2 terms, pulling out common factors :
2 • (x-12)
Step-5 : Add up the four terms of step 4 :
(3x-2) • (x-12)
Which is the desired factorization
Equation at the end of step2:
(x - 12) • (3x - 2) = 0
STEP3:Theory - Roots of a product
3.1 A product of several terms equals zero.
When a product of two or more terms equals zero, then at least one of the terms must be zero.
We shall now solve each term = 0 separately
In other words, we are going to solve as many equations as there are terms in the product
Any solution of term = 0 solves product = 0 as well.
Solving a Single Variable Equation:
3.2 Solve : x-12 = 0
Add 12 to both sides of the equation :
x = 12
Solving a Single Variable Equation:
Step-by-step explanation:
[tex]if \: (x + 12) = (3x + 2) \\ 12 - 2 = 3x - x \\ 2x = 10 \\ x = 5 \\ \\ \\ if(x + 12)(3x + 2) = 0 \\ x + 12 = 0 \: \: \: or \: \: \: 3x + 2 = 0 \\ x = - 12 \: \: \: or \: \: \: x = - \frac{2}{3} [/tex]

What is the coefficient in the expression 40a-61=17
Answer:
a = 1.95
Step-by-step explanation:
40a - 61 = 17
40a - 61 + 61 = 17 + 61
40a = 78
40a / 40 = 78 / 40
a = 1.95

What is the area of a rectangle piece of pavement that is 20 ft wide by 15 yards long
Answer:
300
Step-by-step explanation:
To find the area, you should multiply 20 by 15
Answer: 6,000 square ft
Step-by-step explanation:
w=20 ft
l=100 yd
1 yard = 3 feet
l = 100 yd=100 times 3 ft=300 ft
lw = 300 times 20 = 6,000 square feet

Coach Jones has a rope that is 36 feet long. He wants to divide it into 9 equal parts. Write an equation to find how long each part will be. Use a ? to represent the unknown number. Then solve the equation and explain how you determined the length of each part.
Answer:
36/9= a
and
4
Step-by-step explanation:
you just divide 36 by 9 and you get 4.
What direction will the parent graph move if... f(x - 6) = (x - 6)
Going from f(x) = x to g(x) = f(x-6) = x-6 will move the graph 6 units to the right.
Effectively replacing x with x-6 shifts the xy axis 6 units to the left, giving the illusion the function curve shifts 6 units to the right.
Answer: shifts 6 units to the right.In the figure, MQ , SP and NR intersect at point O. What is the value of x? A. 110° B. 60° C. 70° D. 90°
