What is the product of a+3 and −2a2+15a+6b2?

−2a3+9a2+45a+24b2

−2a3+21a2+45a+24b2

−2a3+9a2+45a+6ab2+18b2

−2a3+21a2+45a+6ab2+18b2

C

Step-by-step explanation:

Given

(a + 3)(- 2a² + 15a + 6b²)

Each term in the second factor is multiplied by each term in the first factor, that is

a(- 2a² + 15a + 6b²) + 3(- 2a² + 15a + 6b²) ← distribute both parenthesis

= - 2a³ + 15a² + 6ab² - 6a² + 45a + 18b² ← collect like terms

= - 2a³ + 9a² + 45a + 6ab² + 18b²

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
