Imagine a 'U' shape
sides are x legnth
base is b legnth
2x+b=25
area is height times base=xb
xb=50
2x+b=25
solve
minus 2x both sides
b=25-2x
sub for b
x(25-2x)=50
25x-2x^2=50
times -1 both sides
2x^2-25x=-50
add 50 both sides
2x^2-25x+50=0
use quadratic formula or something
x=2.5 or 10
A is the answer
Alright, so we'll use the Pythagorean Theorem for this one.
⇒ a²+b²=c²
The hypotenuse of a triangle is represented by c² and we're given the values for a and b. For this triangle, we'll make 15 = a and 20 = b. Plug this into the equation and we'll have (15)<span>² + (20)² = c ². This gives us 625 = c</span>². Solve for c by square rooting both sides of the equation. √(625) = c. We now know that c = 25. To take the perimeter, we add a + b + c ⇒ (15) + (20) + (25) = Perimeter.

9 hours every day for 5 days so you just do 9x5
Answer:
Step-by-step explanation:
The volume of the mentioned object is
Where 
is the base area, which is defined 
, because the base is a square which side is 
units long.
Additionally, we know that the volume of the object is
Replacing the first expression and the volume of the base, we have
Therefore, the expression that represents the height of the volume is
