the first option - 48s + 4.75
Step-by-step explanation:
The approximate width of Alice's backyard is 22.36 in.
Let l be the length of the rectangle and w be the width.
l = 2w
A = 1000 m2 = l*w
1000 m2 = 2w *w
500 m2 = w^2
√500 m2 = √w^2
w = <span>22.360679775 in or 22.36 in</span>
X + 3x = 90 degrees
4x = 90
x = 22.5 degrees
Answer:
Step-by-step explanation:
Set up the slope formula to solve for the unknown:
which simplifies to
which simplifies a bit more to
Multiply both sides by -3 to get rid of the fraction, leaving you with:
6 - s = 15 and
-s = 9 so
s = -9
