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
the answer to your question is
−3x+y=−7
Square root of the area ?
Answer:
- first side: 55 cm
- second side: 60 cm
- third side: 50 cm
Step-by-step explanation:
The problem statement gives all the side lengths in terms of that of the second side. Let s represent the length of the second side in cm. Then the length of the first side is (2s-65), and the length of the third side is (s-10). The perimeter is the sum of all the side lengths:
165 = (2s -65) +s +(s-10)
165 = 4s-75
240 = 4s
60 = s . . . . . . . . second side
2s-65 = 55 . . . . first side
s-10 = 50 . . . . . . third side
In order, the side lengths are 55 cm, 60 cm, 50 cm.
