Step-by-step explanation:
this problem seeks to test our knowledge on word problems and algebra
<u>Solution</u>
let the base be x, and
the height h = 2x+4
We know that area of a triangle is given as
substituting our given values we have
re-arranging we have
we can now find two factors that will add up to give 2 and multiply to give -168
they are 14 and -12
The possible base of the triangle is 14 in
and the height is
I believe that it is 2x^2+1x-2

Answer:
11
Step-by-step explanation:
The rate of change is the ratio of the change in Y to the change in X.
When Y changes from -40 to 4, that is an increase of 44 (4--40=4+40=44), so the change in Y is +44. The corresponding change in X is from -3 to 1, so the change in X is +4 (1--3=1+3=4). The ratio of the change in Y to the change in X is 44/4=11.
Try doing the same computation going from the second row to the third row and you will get the same ratio of 11.
