Answer:
Step-by-step explanation:
(3x – 5)(–x + 4)
(3x)(–x) + (3x)(4) + (–5)(–x) + (–5)(4).
-3x^2+12x +5x -20
-3x^2+ 17x -20
Answer:
2667 dump truck loads
Step-by-step explanation:
To solve this exercise, we must resort to a proportion rule.
Knowing what happened in the first place, how much was needed, a direct proportion will be made with the other accident, be as follows.
Landslide Dump Truck Loads
3 yd ^ 3 -------------------------------------------> 200
40 yd ^ 3 -------------------------------------------> X
X = (40 * 200) / 3
X = 2666.6, that is, for 40 cubic yards of sliding, approximately 2667 dump truck loads are needed.
The 2 numbers cannot be positive but the 2 numbers can be both positive and negative like: 2+(-3)= -1. Both numbers can also be negative like: (-3)-(-2)=-1.
Answer:
The perimeter of the image is 144 inches
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its perimeters is equal to the scale factor
so
The perimeter of the image is equal to the perimeter of the pre-image multiplied by the scale factor
