Answer:if it’s a pretest just guess you don’t need to get it right
Step-by-step explanation:
You can use factors to solve. Determine all the factor pairs of 24, find the two that are two numbers apart.
1, 24 X
2, 12 X
3, 8 X
4, 6 YES!
Algebraic way to solve using Quadratics:
l = 2 + w
A = lw
A = (2 + w)w Substitute (2 + w) for l
24 = (2 + w)w Substitute 24 in for the area
24 = 2w + w^2 Distribute
w^2 + 2w - 24 = 0 Set equal to 0 (put in standard form)
(w + 6) (w - 4) = 0 Factor
w + 6 = 0 and w - 4 = 0 Set each factor equal to 0.
So w= -6 or w = 4 ... -6 makes no sense for a length! So the width must be 4 and the length will be 4 + 2, which is 6.
165 new subs.
22 divided by 4 is 5.5. So approximately 5.5 new subs per day. Multiply that by 30 is 165
For a square, the area is the square of the side length (length x width = area, but in a square length = width). That means the side length is the square root of the area.
In this case the side length is the square root of 121, which is 11. Answer is C.
Answer:
y=x+8
Step-by-step explanation:
y= x+8
8 is your y intercept
and your slope is 1 but it's x
