Answer:
X=22
Step-by-step explanation:
All the angles in every triangle must add up to 180 so we can subtract 23 and 135 from 180 to get 22.
Answer:
g(x)=4x-48
Step-by-step explanation:
f(x)=0.25x + 12
substitute
f(x) with y
y=0.25x + 12
then replace x with y and y with x
x=0.25y + 12
swap equation
0.25y + 12 = x
0.25y = x - 12
divide both sides by 0.25
Y=4x-48

Answer:
x=64
Step-by-step explanation:
* change equivalent to to = *
now we have x² - 16x + x = (x-8)²
step 1 simplify both sides
(x)²=x²
-8x*2=16x
8=64
-16x + x = 15x
now we have x² -15x = x² - 16x + 64
step 2 subtract x² from each side
x² -x² = 0
x² - x² cancels out
now we have -15x = -16x + 64
step 3 add 16x to each side
-15x + 16x = x
-16x + 16x cancels out
we're left with x = 64
