Answer:
x = 44
Step-by-step explanation:
So far, so good.
Now add the opposite of 0.8 to both sides.
0.2x = 8.8
And multiply both sides by 5 (equivalently, divide by 0.2).
x = 44
5.79
3.99 x .45 = 1.7955 = 1.80
3.99 + 1.80 = 5.79
Answer:
9.233 ft, 23.233 ft
Step-by-step explanation:
If the shorter leg is x, then the longer leg is x+14 and the Pythagorean theorem tells you ...
x^2 + (x +14)^2 = 25^2
2x^2 +28x +196 = 625
x^2 +14x = 214.5
x^2 +14x +49 = 263.5
(x +7)^2 = 263.5
x = -7 +√263.5 ≈ 9.23268
The two leg lengths are √263.5 ± 7 feet, {9.23 ft, 23.23 ft}.
