What is the product if a-3 and -2a^2+15a+6b2

Ierofanga [76]

The product if a-3 and -2a^2+15a+6b^2 is: $-2a^3+21a^2+6ab^2-45a-18b^2$

Step-by-step explanation:

In order to find the product of 2 expressions, distributive property can be used.

Given expressions are:

$a-3\\and\\-2a^2+15a+6b^2$

Product of given expressions

$= (a-3)(-2a^2+15a+6b^2)\\= a(-2a^2+15a+6b^2)-3(-2a^2+15a+6b^2)\\= -2a^3+15a^2+6ab^2+6a^2-45a-18b^2$

Combining like terms

$= -2a^3+15a^2+6a^2+6ab^2-45a-18b^2\\=-2a^3+21a^2+6ab^2-45a-18b^2$

Hence,

The product if a-3 and -2a^2+15a+6b^2 is: $-2a^3+21a^2+6ab^2-45a-18b^2$

I am very confused, I need help, please!!!!

seropon [69]

Answer: B

Step-by-step explanation:

A is incorrect because going from -10 to 10 is not 0, it is 20.

C is incorrect because 21 km from sea level is adding 21.

D is incorrect because the total distance biking to school and back is actually 6.2.

B is correct because buying an item for the same price then selling it for the same price results in no increase in profit but consistency therefore being 0.

The area of a trapezoid is 864 cm2. It has a height of 24 cm, and the length

Darina [25.2K]

Answer:

Length of other base = 42 cm

Step-by-step explanation:

h = 24 cm

One of its base a = 30 cm

$Area=864cm^{2}\\\\\frac{(a+b)*h}{2}=864\\\\\frac{(30+b)*24}{2}=864\\\\(30+b)*12=864\\\\30+b=\frac{864}{12}\\\\30+b=72$

b = 72 - 30

b = 42 cm
