\frac{x-7}{x+4} / \frac{x}{x+3} =  \frac{x-7}{x+4} * \frac{x+3}{x} =  \frac{(x-7)(x+3)}{(x+4)(x)}
Remember that dividing by a fraction is the same as multiplying by the reciprocal (or the reverse) of the fraction on the bottom. A restriction on the domain means that x can not be that value. This occurs when the denominator is zero. If (x+4) = 0 or x = o then the denominator will be zero so the restrictions are x = -4,0. The answer is c.

The radius of a circle is 16 millimeters. What is the circle's area?
Kisachek [45]

Answer:

803.84 millimeters²

Step-by-step explanation:

How do we find the area of a circle?

  • The area of a circle is πr², where r = radius. In this case, we have to approximate pi to 3.14.

<u>Solving</u>

  • <u></u>3.14 *16^2
  • 3.14*256
  • 803.84

Therefore, the area is 803.84 square millimeters.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

Find the sale price to the nearest cent.<br><br> $4.30 makeup; 40% discount; 6% tax
katrin [286]

Answer:

Sale price is $2.58.

Paid with tax is $2.73

Step-by-step explanation:

If the make-up is originally $4.30 and you receive a 40% discount. This means you'll pay 60% of the price since 100-40=60.

To find this price, 60% as 0.6 is multplied with the price. 0.6*4.30 = $2.58

This is the sale price.

When you pay you will pay 6% tax or 0.06 of the price. Find this by multiplying $2.58 by 1.06.

2.58(1.06) = $2.73
