the expression is simplifying to 11+2x
Answer:
You keep adding 15.
Step-by-step explanation:
5+15=20
20+15=35
35+15=50
50+15=65
F(x) = (√ x +6) +8
f(x-1) = (√ x-1 +6) -8
=(√x+5) -8
Answer:
The side lengths are 30, 36 and 39.
Step-by-step explanation:
To find the missing side, write a proportion using side lengths from each similar shape. A proportion is an equation that sets equal two ratios.

Find y by cross multiplying numerator and denominator of each fraction.
13y = 39(12)
13y = 468
y = 36
Find the other missing side by repeating the process.

Find y by cross multiplying numerator and denominator of each fraction.
13y = 39(10)
13y = 390
y = 30
The side lengths are 30, 36 and 39.
