The answer is 9
Step-by-step explanation:
set up the equation as 12^2 + b^2 = 15^2
solve the exponents and you get 144 + b^2 = 225
Then subtract 144 from both sides and get 81
After that just do the square root of 81 and you get 9

7.09 Because it goes tens, hundredths, thousandths. Since our problem is nine hundredths the answer will have two numbers. 7 is the whole number so it goes before the decimal. :)
Answer:
$378
Step-by-step explanation:
Full price: 1.00($450) = $450
20% off: 0.20($450) = $90
Sale price (after 20% off): (1.00 - 0.20)($450) = 0.80($450) = $360
Final price, including tax: (1.00 + 0.05)($360) = $378
