Answer:

The answer is 402.

Step-by-step explanation:

First thing to do is substitute the variables.

6(3)^2+(9(8)-2)+8

Now, multiply and subtract what is in the parenthesis.

6(3)^2+(72-2)+8

6(3)^2+70+8

Now, multiply once again.

18^2+70+8

Now, simplify the exponents.

324+70+8=402

What is the discount price os a skateboard that cost $155.80 on sale for 20% off
pshichka [43]
Here's an example of %
20% = 0.2
2% = 0.02

when multiplying with decimals in place you always add up the two periods, 155.8 × 0.2 = 31.16
since the dot is one over for both you add 1 + 1 which equals 2, then when you get 31.16 you move over 2 decimal points, making it 31.16
btw the answer is when you subtract 31.16 from 155.80 which would be 124.64$ for your final cost.
