B - 7x = a - b
Subtract b from both sides.
-7x = a - 2b
Divide both sides by -7.
x =
12. I need the graphs to answer it
11. y = 1/2x - 1
10. The first graph is the best
If you were to write it fully, as an equation, I believe it would look like this:
x²(4x-x) *4x
Therefore allowing you to simplify the area within the bracket into:
x²(3x)*4x
To expand, you simply start on the left and work your way across.
3x³*4x= 12x⁴

Answer: 2f^2 </h3>
Step-by-step explanation:
Remove the parentheses: = ff x 2
Apply exponent rule: f^1+^1x2
Add the numbers 1+1=2 = 2f^2
I hope this is right.
Answer:
-19
Step-by-step explanation:
Use the geometric ratio r=a2/a1
So 117/-13 = -9
-13*-9= 117
117*-9= -1053
