Answer:
Area = 16 in²
Step-by-step explanation:
Represent the length with L and the width with W
We have the following given parameters:
L = 4W
Perimeter = 20
Required
Determine the area.
The perimeter is calculated as thus:
Perimeter = 2(L + W)
Substitute 4W for L and 20 for Perimeter.
20 = 2(4W + W)
20 = 2 * 5W
20 = 10W
Solve for W
W = 20/10
W = 2
Recall that:
L = 4W
L = 4 * 2
L = 8
The area is then calculated as thus:
Area = L * W
Area = 8 * 2
Area = 16
Hence, the area is 16in²
4.5 in. Or 4 1/2 inches just depending how they want you to write it.
(4•2^2+6)/[2-(2.5+4.7)]
22/(2-7.2)
22/-5.2
4.23
Answer:
If x = 0, then the value of the polynomial = 0
Step-by-step explanation:
Given that ;
F(x ) = 5x - 4x^2
Substituting 0 for x we have;
F(0) = 5(0) -4(0)^2 = 0 + 0 = p
