Ise the terms 4, 12a, 6, 2a, and 24 to make equivalent expressions
Sedaia [141]

Answer:

12a + 24 = 6(2a + 4) is the equivalent expressions

Step-by-step explanation:

Given the terms ; 4, 12a, 6, 2a, and 24

There are two terms with unknown = 12a and 2a

but 12a = 2a x 6 .........(1)

from the last term = 24 = 6 x 4 ...........(2)

add both equation 1 and 2 = 12a + 24

12a + 24 = 6(2a + 4) is the equivalent expressions .

to VERIFY; Use a = 2

substitute into the expression ; LHS = RHS

= 12(2) + 24 = 24 + 24 = 48 (LHS)

FOR RHS = 6(2a+4) = 6(2x2 + 4)

= 6(4+4) = 48

Hence LHS = RHS

Write a quadratic function f whose zeros are -3 and -4
dlinn [17]

Answer:

Step-by-step explanation:

Zeros α = -3 and β = -4

Quadratic equation: x² - (α + β)x + αβ = 0

x² - (-3-4)x + (-3)*(-4) = 0

x² - (-7)x + 12 =0

x² + 7x + 12 = 0

A sphere has a volume of 36π in3. What is the radius of the sphere?
amm1812

Answer:

r = 3 inches

Step-by-step explanation:

The formula for the volume of a sphere is the following:

V = (4π/3)r^3

You know the volume so plug that in for V:

36π = (4π/3)r^3

27 = r^3 (multiply by 3/4π to get r^3 by itself)

r = 3 (you take the cube root of r and 27 to get the value of r)

Hope this helps :)
