F(4) is equivalent to 28 because when you plug in 4 for the x, you get 28.

Answer:

f(4)=28

Step-by-step explanation:

Let f(x) = 3x + x², find f(4).

f(x) is a function such that the value of x at any time gives the value of 3x + x².

So when we are given the value of f(x), we just input the value of x in the equation and solve. Assuming were looking for f(0),

f(0) = 3×0 + 0²= 0

From the question given

Let f(x) = 3x + x², find f(4)

we would put x=4 in 3x + x²

This would give 3×4 + 4²=12+16=28

So f(4) = 3×4 + 4²=12+16=28

Anton [14]

Answer: A

Step-by-step explanation:

Given:

Budget = $25

Shoes rental = $5.00

Price per game = $4.00

To find the greatest number of games he played...

↓

First, subtract the rent for the shoes from the budget.

25 - 5 = 20

Second, divide the remaining money or budget by the price per game.

20 ÷ 4 = 5 (greatest number of games played)

Lastly, check if the expense is the same as the original amount of money.

5 (shoes) + 4(5) (number of games played)

5 + 20 = 25 (original amount of money)

Hope it helps!!! Please mark as brainliest. Thank you :D

Answer:

48∛9 ft²

Step-by-step explanation:

The length (L) and width (W) are given by:

$L = 4\sqrt[3]{24}\\ W= 6\sqrt[3]{3}$

Since this is a rectangular region, the area is given by:

$A=L*W=L \\A=4\sqrt[3]{24}* 6\sqrt[3]{3}\\A=24\sqrt[3]{72}\ ft^2$

The answer can be further simplified by factoring as follows:

$A=24\sqrt[3]{72} = \\A=24\sqrt[3]{2*2*2*3*3}= 24\sqrt[3]{2^3*9}\\A=48\sqrt[3]{9}\ ft^2$

The exact area is its simplest form is 48∛9 ft²
