Answer:
A dilation with a scale factor of 2
Step-by-step explanation:
We know this because the coordinates of ABCDE were multiplied by 2
ex A coordinates are (4,-4) b coordinates are (8,-8) the coordinates were multiplied by 2
8/4=2
-8/-4/=-2
Answer is 76 - 2x
When solving these problems, you have to look at each individual word step by step
76 is being decreased
decreasing means something is being taken away from it, so this must be subtraction
76 -
by twice a number
so something is definitely being multiplied by 2
76-2
Now since we don't know this number that is being multiplied by 2 , you would have to put x in it's place.
76-2x
Answer:
(x + 3)(x + 2) = 9
x^2 + 5x + 6 = 9
x^2 + 5x = 3
Step-by-step explanation:
length * width = area
(x + 3)(x + 2) = 9
Expand
x^2 + 5x + 6 = 9
Subtract 6 from both sides
x^2 + 5x = 3
