The answer would be $40-D=$5.19 because since D equals something we have no clue about, we need to subtract 40 from 5.19 to get our answer for D if that’s what they were asking. For now, we would find the equation which is 40-D=5.19!

I hope this helped! Mark me Brainliest! :) -Raven❤️

Consider the functions f(x) = 2x - 3 and g(x) = 6 + 8/x. Solve for f(g(4))
ExtremeBDS [4]

Answer:

13

Step-by-step explanation:

Given the equations f(x) = 2x - 3 and g(x) = 6 + 8/x.

We want to find f(g(4))

Essentially, what we are doing, is plugging in 4 into x for g(x) and the outcome of that is what we plug into x for f(x)

So first lets plug in 4 into x for g(x)

g(x) = 6 + 8/x.

We want to find g(4)

g(4) = 6 + 8/4

First divide 8 by 4

g(4) = 6 + 2

Then add 6 and 2

g(4) = 8

Now that we have found g(4) we want to plug the value of g(4), so 8 into f(x)

f(x) = 2x - 3

we want to find f(8)

f(8) = 2(8) - 3

* multiply 2 and 8 *

f(8) = 16 - 3

* subtract 3 from 16 *

f(8) = 13

and we are done!

So we can conclude that f(g(4)) = 13

Question:
12345 [234]

Answer:

A. Area in square inches =  1760 square inches

B. Area in square feet = 12.2 square feet

C. 1 square inch = \frac{1}{144} feet

Step-by-step explanation:

Given,

Length of the rectangle (l) = 55 inches

Breath of the rectangle (b) = 32 inches

A. Area of the rectangle = length × breath

⇒ 55 × 32

⇒ 1760 square inches

Area in square inches =  1760 square inches

B. 1 foot = 12 inches

1 inch = \frac{1}{12} feet

1 square inch = \frac{1}{144} feet

∴ 1760 square inches = \frac{1760}{144} feet

⇒ 12.2222 square feet

Area in square feet = 12.2 square feet

C. 1 square inch = \frac{1}{144} feet
