Step-by-step explanation:

(4 {x}^{2}  - 3x - 4) - (3 {x}^{2}  + 4x - 8) \\  \\  = 4 {x}^{2}  - 3x - 4 - 3 {x}^{2}  - 4x + 8 \\  \\  = 4 {x}^{2}  - 3 {x}^{2}  - 3x - 4x - 4 + 8 \\  \\  =  {x}^{2}  - 7x + 4

Thus option B is the correct answer.

Using the standard 28/36 guidelines, what is the maximum mortgage payment allowed for someone with
Nitella [24]

The maximum mortgage payment allowed for someone with an annual salary of $83,750 would be $2512.50 per month.

<h2><u>What is the standard 28/36 guidelines?</u></h2>

To determine, using the standard 28/36 guidelines, what is the maximum mortgage payment allowed for someone with an annual salary of $83,750, the following calculation must be made:

  • Annual salary x 36% / months = X
  • ((83750 x 36) / 100) / 12 = X
  • (3,015,000 / 100) / 12 = X
  • 30150 / 12 = X
  • 2512.50 = X

Therefore, the maximum mortgage payment allowed for someone with an annual salary of $83,750 would be $2512.50 per month.

Find the area of the circle to the nearest whole number, if necessary!
astra-53 [7]

Answer:

The circle has an area of about 1385 square mm.

Step-by-step explanation:

Let's recall that circles have an area that can be found with the following formula:

A=\pi r^{2}

where r is the radius of the circle.

Now, focus your eyes on the circle. We are shown that the diameter of this circle is 42 mm, but we only want the radius. Since the radius is half the diameter, the radius is 21 mm. Now, we can solve for the area of the circle.

A=\pi (21)^2\\A=441\pi \\A=1385.44236...

So, to the nearest whole number, the area of the circle is 1385 square mm.
