Answer:
together their year=56 years
younger then his mother=24
56-24=32
For this problem, you're finding volume. The expression for volume is l•w•h (length times width times height).
Answer:
B.) See attachment below

Answer:
The diagonal of the rectangle is approximately 42.5 inches.
Step-by-step explanation:
The area of a rectangle is given by the following formula:
area = width*length
In this case the width = 2*length, therefore we have:
area = 2*length²
722 = 2*length²
2*length² = 722
length² = 361
length = sqrt(361) = 19 inches
width = 2*length = 2*19 = 38 inches
The diagonal forms a right triangle with the sides of the rectangle, where it is the hypotenuse. Therefore we can use Pytagora's theorem:
diagonal = sqrt(length² + width²)
diagonal = sqrt(19² + 38²) = 42.485 inches
The diagonal of the rectangle is approximately 42.5 inches.
Answer:
B is the answer
Step-by-step explanation:
the Pythagoras therom is
p^2+b^2=h^2
9^2+12^2=15^2
81+144=225
225=225 (true)
