Expand the left side:
(3x + 2) (5x + 1) = 15x² + 10x + 3x + 2 = 15x² + 13x + 2
Then a = 15 and b = 13, so a - b = 2.
You start by finding the slope : y2 - y1 / x2 - x1
2 - 8 / 4 - (-16)
- 6 / 20
m = - 3 / 10
Point slope form : y - y1 = m( x- x1 )
You can pick either of the coordinates and substitute them in
POINT SLOPE FORM EQUATION : y - 8 = -3/10 ( x + 16 )
That's already rounded to the nearest hundredth, so the answer is 3419.46.
The picture below will help you.
Cube has 4 lateral faces
4s² = 676 = 4 × 169
s² = 169
s = 13
your answer is 13
So "of" means multiply and 30% is .3 so multiply .3 by the 240 times and u get... 72!
