Step-by-step explanation:

Square feet refer to the area of the triangle. Using the area formula (1/2bh), the area is calculated to be 4.375 square feet. If each square foot costs $.40 to make, then the correct process is to multiply 4.375 by .40, making the correct answer $1.75.

The area of a rectangle with 2 1/2 as the width and 10 feet as the length
Tanya [424]
The formula for the area of a rectangle is:
A=wl
w = width
l = length

First, we have to convert 2 \frac{1}{2} into an improper fraction, then into a number. The improper fraction would be \frac{5}{2}. Let's convert that into a decimal.
5/2=2.5

Let's multiply
2.5*10=25
The area of the rectangle would be 25 feet!

Please help!! <br><br><br> Find the inverse of y=7x-10. Is the inverse a function?
kolezko [41]

Answer: f^{-1} (x) = \frac{x+10}{7}

Step-by-step explanation:

To find the inverse , all we need do is to make x the subject of the formula.

y = 7x - 10

Add 10 to both sides

y + 10 = 7x

divide both sides by 7

Therefore:

x = y + 10 / 7 , that is

f^{-1} (x) = \frac{x+10}{7}

Minchanka [31]

Answer:

x=0 or x=−4

Step-by-step explanation:

Let's solve your equation step-by-step.

(x+2)2=4

Step 1: Simplify both sides of the equation.

x2+4x+4=4

Step 2: Subtract 4 from both sides.

x2+4x+4−4=4−4

x2+4x=0

Step 3: Factor left side of equation.

x(x+4)=0

Step 4: Set factors equal to 0.

x=0 or x+4=0

x=0 or x=−4
