Answer:
9x² - 12x + 4
Division Property
Step-by-step explanation:
(3x-2)² = (3x-2)(3x-2)
using the foil method we get:
9x² - 6x - 6x + 4
combine 'like' terms to get:
9x² - 12x + 4
2x = 10 To get 'x' by itself, since it's being multiplied by 2 we must do the inverse operation which is division
If we divide one side of an equation by 2 we must do the same to the other side, giving us:
x = 10/2 which is x = 5
Answer:
Use a matrix equation to solve the system of linear equations: -2x + 4y= 2, -3x+7y=7 *
<h3>I'll teach you how to solve k/7.4+84.2=35.1</h3>
--------------------------------------------------------
k/7.4+84.2=35.1
Subtract 84.2 from both sides:
k/7.4+84.2-84.2= 35.1-84.2
Simplify:
k/7.4= -49.1
Multiply both sides by 7.4:
7.4 k/7.4= 7.4(-49.1)
Simplify:
k = -363.34
Your Answer Is k = -363.34

Answer:
D. 38.5 sq. units
Step-by-step explanation:
The formula for the area of a triangle is A=bh(1/2)
So to solve, first multiply the base, by the height: 11*7=77
Then, multiply by 1/2 or divide by 2.
You get 38.5
That's your answer!
Hope this helps!
