8x( 47 ) = 8x + 7x
8x( 47 ) = 8x( 2 ) - x
8x( 47 - 2 ) = - x
8x( 45 ) = - x
360x = - x
x = -360x
I don't think the question can be done
Is the question wrong?
because there's no answer other than 0.
Answer:
72 units³
Step-by-step explanation:
length = 12 units
height = 4 units
width = 3 units (8 - 5 = 3)
12 x 3 x 4 = 144
144 / 2 = 72
Answer:
4 seconds
Step-by-step explanation:
When the ball is on the ground h = 0, hence
- 16t² + 64t = 0 ( solve for t )
factor out - 16t
- 16t(t - 4) = 0
equate each factor to zero and solve for t
- 16t = 0 ⇒ t = 0
t - 4 = 0 ⇒ t = 4
the 0 solution is the height of the ball before being hit and
the time the ball takes to hit the ground is 4 seconds
So area is base x height:
5(x+2)=20
5x+10=20
5x=10
x=2
its A
