X = -1, x = 3
Sooooo, 2 x -1 = -1^2-3
which means, -2 = 1 - 3 which is -2 = -2
Then we also have 2 x 3 = 3^2 - 3
which means, 6 = 9 - 3 which is 6 = 6
So x = -1 and x = 3
I'll help you with #7, and hopefully then you will be able to do #8 on your own. the formula for the volume of a pyramid and cone is the area of the base times the height of the figure divided by three. knowing this, we must first find the area of the base. since it is a square, we need to multiply the length times the width. (6 • 6 = 36) then you multiply that times the height of the figure (36 • 4 = 144) finally, we need to divide that by three (144 divide by three is 48.) so the answer is b. hope this helped :$
Answer:
$180
Step-by-step explanation:
Since the discount is 40 percent and is also $72, We will cross multiply. 72 x 100 = 40 x what?
7200/40 = 180
The mirror was originally $180.
Use the law of sines
11/sin50°=13/sinθ
11/0.766=13/sinθ
11sinθ=13(0.766)
11sinθ=9.958
sinθ=9.958/11
sinθ=0.9052727
use arcsin on your calculator
θ=64.86°
