To find the dimensions you can just factor the equation...
x^2+4x-21
x^2-3x+7x-21
x(x-3)+7(x-3)
(x+7)(x-3) and this is equal to LW or WL
And note that x>3 for any possible solution.
Answer:
B
Step-by-step explanation:
54/6=9 meaning each face has an area of 9.
Meaning each side has an area of 3.
That means the volume is 3*3*3=27
Answer:
42
Step-by-step explanation:
the is range is 42

ftfft
Step-by-step explanation:
<h3><u>The value of the first number, x, is equal to 18.</u></h3><h3><u>The value of the second number, y, is equal to 90.</u></h3><h3><u>The value of the third number, z, is equal to 77.</u></h3>
x + y + z = 185
y = 5x
z = y - 13
Because we already have a value for y, we already have a value for z. We can now solve for a value of x.
x + 5x + 5x - 13 = 185
Add 13 to both sides.
x + 5x + 5x = 198
Combine like terms.
11x = 198
Divide both sides by 11.
x = 18
Because we have a value of x, we can solve for the exact values of y and z.
y = 5(18)
y = 90
z = (90) - 13
z = 77
