7.1% subtract the final price by the original price to find the increase and then divide the increase by the original price.

Explanation:

Find the increase

3.75−3.50=.25

Then divide the increase by the original amount

.253.50=.0714285

To change to a percent multiply by 100 and round off to significant numbers

# .0714285 = 7. 14285% or 7.1% or just 7%

Answer:

AN = 16 units

Step-by-step explanation:

So we can use the fact that \frac{AN}{FN} =\frac{OR}{FR}

  • Since this is an isosceles triangle, segments FO and FR are both equal to 7

Manipulating the equation above to solve for AN we have AN = \frac{(FN)(OR)}{FR}

  • Substituting in the known values we have AN=\frac{(10)(11.2)}{7} =16

Ostrovityanka [42]

Answer:

(x+8)²

Step-by-step explanation:

x² + 16x + 64 = (x+8)²

(x+8)² = (x+8)(x+8) = x*x + x*8 + 8*x + 8*8 = x² + 8x + 8x + 64

         = x² + 16x + 64
