Answer:
(x-9)(x²+9x+81); it'll give a difference of cubes
Step-by-step explanation:
Generally, the difference of cubes formula is (a³-b³)=(a-b)(a²+ab+b²), and the third option is the only one which fits it; with "a"= x and "b"= 9.
*The sum of cubes formula is (a³+b³)=(a+b)(a²-ab+b²); for future reference.
Answer:
10
Step-by-step explanation:
<em>Since it given that:</em>
<em>x = 7 and y = 3</em>
<em>We can substitute x and y:</em>
<em>(7-3) + 2(3)</em>
<em>7 - 3 = 4</em>
<em>4 + 2(3)</em>
<em>2(3) = 6</em>
<em>4 + 6 =10</em>
<em>Thus the answer is 10.</em>

76 granola bars
to solve this, you need to multiply 15 by 5 for the big boxes and 8 by 2 for the small boxes. 15 x 2 = 60 and 8 x 2 = 16, therefore adding them together gets you 76.
12/15 = x/100
Multiply 12 x 100 to get 1,200/15 is 80.
Because 25 x 4 = 100, you divide 80 by 4.
Your answer is 20.
