Answer:
See below.
Step-by-step explanation:
Variables:
L = length
W = width
P = perimeter
Equations:
L = W + 13
P = 2(L + W)
P = 2(W + 13 + W)
2(W + 13 + W) = 226
2(2W + 13) = 226
2W + 13 = 113
2W = 100
W = 50
L = W + 13 = 50 + 13 = 63
The length is 63 cm, and the width is 50 cm.

Answer:
The value of the discriminant = 132
Step-by-step explanation:
4x^2 - 2x - 8 = 0
Using the discriminant
b^2 - 4ac
a = 4
b = -2
c = -8
Using the coefficients with also adding the signs before each
Insert the values
b^2 - 4ac
= (-2)^2 - 4 * 4 * (-8)
= 4 - 4 *4 * -8
= 4 - 16 * -8
= 4 - -128
= 132
The value of the discriminant is 132
