Answer:
15
Step-by-step explanation:
x/2 + 6 / 3 = 4.5
x/2 + 6 = 4.5 *3
x/2 = 13.5 - 6
x = 7.5 * 2
x = 15

Answer:
a) 9a(x - 3b) - 4(x - 3b) = (9a - 4)(x - 3b)
b) 5a(2b - 3) - 4(2b - 3) = (5a - 4)(2b - 3)
c) x(2h - k) + 3y(k - 2h)
= x(2h - k) - 3y(2h - k)
= (x - 3y)(2h - k)
Step-by-step explanation:
Answer:
x³ - 5x
Step-by-step explanation:
note (h - g)(x) = h(x) - g(x), thus
h(x) - g(x)
= x³ - 2x - 3x ← collect like terms
= x³ - 5x
Given
Your family has a circular swimming pool.
The radius of the pool is 9 feet and and its depth is 4 feet.
Find out the volume of the pool.
To proof
As depth is given in the question that means the shape of the swimming pool
is cylinder.
Formula
where r = radius
h = height
now
radius of the pool is 9 feet and and its depth is 4 feet.
put all the values in the above equation
we get
use 3.14 to approximate pi
we get
= 1017.4 ( approx )feet²
Hence proved
