Answer:
-5 & 1
Step-by-step explanation:
[x² + 2(x)(2) + 2²] - 2² - 5 = 0
(x+2)² - 4 - 5 = 0
(x+2)² = 9
x+2 = +/- 3
x+2 = 3 x = 1
x+2 = -3 x = -5

Answer:
225, 225 and 252 meters
Step-by-step explanation:
Let length of the 2 equal parts be each x m, then:-
2x + x + 27 = 702
3x = 702 - 27 = 675
x = 675/3
x = 225
So lengths of each parts are 225, 225, 252
Answer:
a = 55/6
Step-by-step explanation:
<u>Solving in steps:</u>
- 3/5a = 5 1/2
- 3/5a = 11/2
- a = 11/2 : 3/5
- a = 11/2*5/3
- a = 55/6 or 9 1/6
