Must include an explanation !! solve for x
1 answer:
Answer:
x=5
Step-by-step explanation:
Volume of a rectangular prism=b x l x h
Set up you equation
120=(4 x 12 x
)
Multiply inside the parentheses
120=(48x)
Multiply by
120=24x
Divide by 24 on both sides
5=x
Check you answer
Volume of a rectangular prism=b x l x h
Set up your equation
(12 x 5 x 4)
Multiply inside the parentheses
(240)
Multiply by
V=120yd³

Answer:
3
Step-by-step explanation:
Long story short it's 3, how do I know without calculating? because this is the most common example used when people start learning about the Pythagorean theorem. 3^2 + 4^2 = 5^2
But anyways here is how to solve it
The formula for these questions is a^2 + b^2 = c^2, otherwise known as the Pythagorean theorem. a and b represent the sides that are going vertically and horizontally, doesn't matter which is which. c is the line going down diagonally, also known as the hypotenuse.
So here
a^2 + b^2 = c^2, replace b or a doesn't matter with 4 and c with 5 specifically.
a^2 + 4^2 = 5^2, now just solve for a
a^2 + 16 = 25
a^2 = 9
a = 3
