Answer:
It's D: 3x - 12 ≤ 8x + 13
Step-by-step explanation:
<u>The first step in this inequality is to take out the parentheses so you multiply 3 by x and -4.</u>
Answer: 5 by 12
Step-by-step explanation:
Let's call the dimensions of the rectangle w and w+7
The area is 60, so we can do 60=w(w+7)
60=w^2+7w
w^2+7w-60=0 factor the quadratic equation
(w-5)(w+12)=0
w-5=0, w=5
w+12=0, w=-12
Since the length of a rectangle cannot be negative, w=5
the dimensions of the rectangle are 5 and 12
-33 2/3
