Look at the picture.
We have the similar triangles (AAA). Therefore the lengths of the sides are in proportion:
<em>multiply both sides by 8</em>
Answer:
you have to multiply two variables to get the first variable that not the complete question.
Step-by-step explanation; f(x)=(2x-4)
The difference is whether the exponent attaches to just the 2 or to the negative sign as well
-2^4 = - (2x2x2x2) = -16
(-2^4) = -2 x -2 x -2 x -2 = +16
Answer:
x equals 13
10 + x = 23
x=23-10

-5x = -1
step 3 : divide -5 on both sides
x = -1 / -5
x = 1/5
