There are 60 minutes in one hour, thus, 45 miles per hour is 45 miles per 60 minutes, thus
Answer:
Height = 20 ; Base = 5
Step-by-step explanation:
Triangle Area = Base x Height x 1/2
50 = 1x × 4x × 1/2
50 = 4x^2 × 1/2
50 = 2x^2
25 = x^2
x=5
Height equals to 4x -> 4 × 5 = 20
Base equals to x -> 1 × 5 = 5
for the expression to give a positive results then x just be a negative number
or zero
x<=0
Answer:
16πa²b²c²
Step-by-step explanation:
r = 2abc
SA = 4πr²
= 4π x (2abc)²
= 4π x 4a²b²c²
= 16πa²b²c²
