Answer:
the answer is c
Step-by-step explanation:
Since BD is a perpendicular bisector of AC, then ADC forms an isisceles triangle with AD = DC.
Thus 8x - 15 = 57
8x = 57 + 15 = 72
x = 72/8 = 9.
Let w represent width of the rectangle.
We have been given that the length of a rectangular prism is 1 more than three times the width w. So length of the rectangle would be
.
We have been given that the volume of the prism is
.
We know that volume of rectangular prism is width times length times height.
So we can set an equation as:



Let us factor out w from numerator.





Now we will cancel out
from numerator and denominator.

Therefore, the height of the prism is
units.
Present age of Justin=14
Present age of Sam=11
<u>Step-by-step explanation:</u>
Let the present age of Sam=x
Given that Justin is 3 years older than Sam
present age of Justin=x+3
Age of Sam 3 years ago=x-3
Age of Justin two years hence=x+3+2=x+5
given that after 2 years Justin's age will be twice that of Sam's age three years ago
therefore

Present age of Sam=x=11
Present age of Justin=x+3=11+3=14
