The answer is the first one because you have to multiply the outsider five to the other numbers inside the parenthesis. You don't add them or subtract them because they don't have the same variable
So 9% of 13 is 1.17
so then you go $13 - $1.17 and your answer is $11.83
1.
1.2 x^4 ( 4 x² + 3 x + 1 ) = 4.8 x^6 + 3.6 x^5 + 1.2 x^4
2.
( 4 x - 3 ) ( 2 x² - 7 x + 1 ) = 8 x³ - 28 x² + 4 x - 6 x² + 21 x - 3 =
= 8 x³ - 34 x² + 25 x - 3
3.
( x² + 4 x - 3 ) ( 2 x² + x + 6 ) =
= 2 x^4 + x³ + 6 x² + 8 x³ + 4 x² + 24 x - 6 x² - 3 x - 18 =
= 2 x^4 + 9 x³ + 4 x² + 21 x - 18
<span>Use scientific notation to find the product of 20.5 × 10 7 and 0.000036
the product of these 2 is 7380</span>
Answer:
560 boxes
Step-by-step explanation:
.25 * 1.75 * 2.5 = 1.09375
1/8 ^3 = 0.001953125
1.09375/0.001953125 = 560
