Answer: g(h(3)) = 59

Step-by-step explanation:

Well if its x^3 I assume it is because you wrote other coefficients before the variable.

2(3) - 2 = 6-2 = 4

So 4 is the x input for h(x)

4^3 -5 = 64-5 = 59

Sarah can eat 45 blueberries in 2 minutes. If she eats blueberries for 45 minutes straight, how many did she eat?

BARSIC [14]

Answer:

1012

Step-by-step explanation:

She eats 1012 because:

If she eats 45 in 2 minutes then she eats 22.5 in 1 minute.

This is because 45 ÷ 2 = 22.5

Sarah eats blueberries for 45 minutes so we multiply 22.5 by 45

22.5 × 45 = 1012.5

She ate 1012 full berries.

The perimeter of the triangle below is 97 cm.

Sloan [31]

Answer:

The length of EF = x = 18 cm

Option A is correct.

Step-by-step explanation:

Ware given perimeter of triangle = 97 cm

We need to find length of EF = x = ?

The length of EG = x+7

The length of EF = x

The length of GF = 3x

The formula used is: $Periemter \ of \ triangle= Sum \ of \ all \ sides \ of \ triangle$

Putting values and finding x i.e length of EF

$Periemter \ of \ triangle= Sum \ of \ all \ sides \ of \ triangle\\97=x+7+x+3x\\97-7=5x\\5x=90\\x=\frac{90}{5}\\x=18 \ cm$

So, value of x=18 cm

The length of EF = x = 18 cm

Option A is correct.
