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: $-2a^3+21a^2+6ab^2-45a-18b^2$

Write the standard equation of a circle with center (2, −5) and radius 16.

astra-53 [7]

The standard equation of circle when center is (h,k) and radius is 'r'

$\left ( x - h \right )^{2} + \left ( y - k \right )^{2} = r^{2}$

h = 2 and k = - 5, radius = 16

So equation of the circle is given by

$\left ( x - 2 \right )^{2} + \left ( y - (-5) \right )^{2} = 16^{2}$

$\left ( x - 2 \right )^{2} + \left ( y + 5) \right )^{2} = 256$

-23.26

.42

22.84 - 22.42 = .42

23.26 - 22.84 = .42

Instead of 3.14 use 3 and if you can show work that would be great

LUCKY_DIMON [66]

$\textit{circumference of a circle}\\\\ C=2\pi r~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ r=6 \end{cases}\implies C=2\pi (6)\implies C=12\pi \implies C= \begin{cases} \stackrel{\pi =3}{36}\\\\ \stackrel{\pi =3.14}{37.68} \end{cases}$

How can you use subtraction to complete an addtion pattern

IceJOKER [234]

Answer:Identity Property

Step-by-step explanation:

If you are given a equation like this:

5+__=35 you can us 35 and subtract 5 to figure out the answer

30

<u>- 5</u>

30

which is 30.This could also be shown as the Identity Property.
