As points, x-intercepts take the form
, so to find the intercepts we can set
and solve for
.
From the first equation alone, we already know that
is a solution, which means one intercept is
.
The second equation gives
so that the second intercept occurs at
.
So if
and
, we have
, giving C as the answer.

Step-by-step explanation:
The formula for calculating percentage is
The "part" is the electricity payment.
The "whole" is Ramon's earnings.
X^2 - 16x + 56 = 0
= (x - 8)^2 - 64 +56= 0
= (x - 8)^2 - 8 = 0
x^2 - 8x + 11 = 0
(x - 4)^2 - 16 + 11
(x - 4)^2 - 5 = 0
(x + 15)(x + 5) = 96
x^2 + 20x + 75 = 96
(x + 10)^2 - 100 + 75 = 96
(x + 10)^2 = 96 +25 = 121
taking square roots:-
x + 10 = 11
x = 1
The longest diagonal is about 8.9 inches. The longest length is going to be between the two longest lengths, the width and the height. The Pythagorean theorem is a^2 + b^2 = c^2. Plug the width and height into a and b of the Pythagorean equation. (4)^2 + (8)^2 = c^2. Now simplify the equation. 16 + 64 = c^2. 80 = c^2. Now find the square root of each side. (sqrt)80 = (sqrt)c^2. If you simplify this, you will find that c is equal to about 8.9 inches.
