Answer:
3.77
Step-by-step explanation:
A= L × W
52=(W + 10)W
52= W^2 + 10W
0 = W^2 + 10W - 52
Factor from here using quadratic formula to find the roots:
W = 3.77
or
W = -13.77
Dimensions of a shape cannot be negative, therefore it's approximate width is 3.77yd.
Answer:
well it's logical to assume for every 1 minute I run is x amount of a mile. so x will be be minutes and y is mile. because you don't say for every 1 mile I run is 10 minutes. it doesn't make sense that way.
Step-by-step explanation:
answer is b
A-b=8
2a+3b=51
2a-2b=16
2a+3b=51
Subtract both
-5b=-35
b is 7 and a is 15
The answer is 101.38 or 101.380 : )
