Answer:
A = 693
Step-by-step explanation:
The shape presented is a parallelogram, and the formula for this is:
A = bh
The "b," is the base (21) and the "h," is the height (33), so plug this in:
A = (21)(33)
A = 693
X^2-9x=-8
x^2-9x+8=-8+8
x^2-9x+8=0
(x-8)(x-1)=0
x-8=0
x-8+8=0+8
x=8
x-1=0
x-1+1=0+1
x=1
There are 2 solutions, which are 1 and 8
100 3/4 x 75 1/2
25 x 3 x 75 1/2. (Divided by 4 to 100 and 4 to get 25)
25 x 3 x 75 1/2 ( multiple everything on top)
5625/2 ( then divided normally)
2812.5 or 2812 1/2
