Sorry man
Answer:
Width is 10ft and length is 6ft.
Step-by-step explanation:
The area of a shape is the amount inside a shape. It is found using multiplication or A = l*w. Since the width is w and the length is 4ft less than its width or w - 4, use these expressions in the area formula to find their amount.

Subtract 60 from both sides and factor the quadratic to solve for w.

Set each factor equal to 0 and solve.
w - 10 = 0 so w = 10
w + 6 = 0 so w = -6.
Since w represents a length or distance it cannot be negative, this means the width is 10. The length which is w - 4ft is 10 -4 = 6. The length is 6 ft.
Hey there!
Answer = -21
Explanation:
Let's solve your equation step-by-step.
x + 7 = -14
Subtract seven from both sides:
x + 7 - 7 = -14 - 7
x = -21
So therefore, that is how you found your answer: x = -21
Answer:
176 feet
Step-by-step explanation:
Answer:
0
Step-by-step explanation:
If you think in degrees easier than in radians, then make this conversion.
pi = 180 degrees
(3/2)*pi = (3/2) * 180 = 180 * 3/2 = 270
Sin(270) = -1
cos(270) = 0
==========
sin(270) * cos(270) = -1 * 0 = 0
