Answer:
3) 30 ft
4) 4.8 inches
6) Perimeter = 16 Area = 24
7) Perimeter = 28 Area = 32
8) Perimeter = 29 Area = around 50
First you distribute the 3
(3x-12) (x+5)=0
then you set each equation equal to zero
3x-12=0 & x+5=0
then you solve for x
x =4, -5
We have 4(x^2 - 2x + 4) - 7 = 4x^2 - 8x + 16 - 7 = 4x^2 - 8x + 9;
So, 4x^2 - 8x + 9 = <span>ax^2+bx+c
;
The value of b is -8.</span>
Answer:
Here are a few:
- 14.32 - 8.98
- -8.98 + 14.32
<u>- 8.98</u>
Hopefully this made sense and is the correct way to solve your problem! :)
84.5 inches 1 ft
---------------- * ---------------- = 7.0 ft (rounded to the nearest tenth)
1 12 inches
