Question

Which expressions have a value of 60 when h=3? Choose two correct answers.

Answer 1

Answer:

(1) & (3)

Step-by-step explanation:

Given

List of options

Required

Select which is equal to 60 when h = 3

To do this, we simply substitute 3 for h in all of the options.

1.

$(h + 1)^3 - 4$

$(3 + 1)^3 - 4$

$4^3 - 4$

$64 - 4$

$60$

Hence:

$(h + 1)^3 - 4= 60$

2.

$(4h)^2 + 36$

$(4*3)^2 + 36$

$(12)^2 + 36$

$144 + 36$

$180$

Hence:

$(4h)^2 + 36=180$

3.

$4h^2 + 24$

$4*3^2 + 24$

$4 * 9 + 24$

$36 + 24$

$60$

Hence:

$4h^2 + 24 = 60$
