Answer:

15^4+2^3−8^2−22−15

Step-by-step explanation:

(3^2−2−3)(5^2+4+5)

Distribute:

<u>3(5^2+4+5)</u> ⋅ ^2−2(5^2+4+5) − 3(5^2+4+5)

15^4+12^3+15^2 <u>− 2(52+4+5)</u> − 3(52+4+5)

15^4+12^3+15^2 − 10^3−8^2−10 <u>− 3(52+4+5</u>)

15^4+12^3+15^2 − 10^3−8^2−10 − 15^2−12−15

Combine like terms:

15^4<u>+12^3−10^3</u>+15^2−8^2−15^2−10−12−15

15^4+2^3<u>+15^2−8^2−15^2</u>−10−12−15

15^4+2^3−8^2<u>−10−12</u>−15

15^4+2^3−8^2−22−15

15^4+2^3−8^2−22−15

hope it helps :)

Alex purchased a new car for $28000. The car depreciates 7.25% each year. what will the price be in 5 years?
dalvyx [7]
Use the depreciation formula.

\sf p(1-r)^n

Where 'p' is the principal value, 'r' is the rate it depreciates, and 'n' is the time. Just plug in what we know:

\sf 28000(1-0.0725)^5

Simplify by subtracting:

\sf 28000(0.9275)^5

Simplify the exponent:

\sf 28000(0.6864)

Multiply:

\sf\approx\boxed{\sf\$ 19219.20}
