The answer is 480 because the equation is always length times width.
Answer:
x=4
Step-by-step explanation:
4x4x4=64
4x4=16
16 x 4 = 64
Answer:
The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.

Answer:
x = 5
Step-by-step explanation:
In ΔPQR, PR is extended through point R to point S.
m∠PQR=(2x+1) ∘
m∠QRS=(10x−10) ∘
m∠RPQ=(3x+14) ∘
Hence, we solve using Exterior angle Theorem.
This means that:
m∠QRS = m∠PQR + m∠RPQ
(10x - 10)° = (2x + 1)° + (3x + 14)°
10x - 10 = 2x + 1 + 3x + 14
Collect like terms
10x - 2x - 3x = 1 + 14 + 10
5x = 25
x = 25/5
x = 5
