6h+5(h-5)= 52
Mutiply the bracket by 5
(5)(h)(5)(-5)= 5h-25
6h+5h-25= 52
move -25 to the other side
sign changes from -25 to +25
6h+5h-25+25= 52+25
6h+5h= 77
11h= 77
divide by 11
11h/11= 77/11
Cross out 11 and 11, divide by 11 and becomes 1*1*h= h
h= 7
Answer: h= 7

16
Step-by-step explanation:
20 + 16=36 36x2=72
Answer:
w = 5 , w = -5
Step-by-step explanation:
w^2 = 25
Take the square root of each side
sqrt(w^2) = ± sqrt(25)
w = ±5
The answer is 39.470 because 39.472 is far from 39.450 and it’s 2 numbers passed 39.470.
Answer:
I think its B.) Yes, because the ratios simplify to the same number., sorry if it's wrong
Step-by-step explanation:
50/10 = 1/5
60/12 = 1/5
70/14 = 1/5
80/16 = 1/5
