Answer:x=8 or x=-4

Step-by-step explanation:

x²+(x+7)² = (x+9)²

x²+(x+7)(x+7) = (x+9)(x+9)

x²+x²+7x+7x+49 = x²+9x+9x+81

2x²+14x+14x+49 = x²+18x+81

2x²-x²+14x-18x = 81-49

x²-4x = 32

(x²-4x)-32 = 0

(x+2x)(x-2x)-32 = 0

x²+2x²-2x²-4x-32 = 0

x²-4x-32 = 0

(x-8)(x+4) = 0

(x-8) = 0 or (x+4) =0

x = 8 or x = -4

Answer:

620.14

Step-by-step explanation:

Original Equation:

\frac{4y}{1.025^4}+y-2y(1.05)^2=1500

Calculate exponents

\frac{4y}{1.103812890625}+y-2y(1.1025)=1500\\

Simplify:

3.6238025791990193084270042653997y + y - 2.205y = 1500

Add like terms

2.4188025791990193084270042653997y \approx 1500

Divide both sides by 7.012

y\approx 213.91y\approx620.14

Answer:

700 miles

Step-by-step explanation:

Since the scale is 0.5 and she's 7 inches away on the map, you divide 7 by 0.5 and get 14. Then, you multiply 14 by 50 because each inch is 50 miles.
