Answer:
See below
Step-by-s.ep explanation:
6. Let the 3 integers be k-2, k and k+2.
So k(k+2)-k(k-2) = 28
k^2 + 2k - k^2 + 2k = 28
4k = 28
k = 7.
So the 3 integers are 5, 7 and 9.
- I have answered this in your last question. (16).
Base is 12 feet square so 12 *12 = 144 square feet
each triangle has base of 12 feet and height of 8 feet
area of triangle = 1/2 x base x height = 1/2 x 12 x 8 = 48 square feet
48 x 4 triangles = 192 square feet
total: 192 + 144 = 336 square feet
Move the 8 over
-x=3x-8
Move the 3x over
-x-3x=8
-4x=8
Divide by -4
x=-2
Answer:
d=3d-5 or the other way around
