Offering 15 points. 8th grade algebra, very easy. answer asap !

Step-by-step explanation:

A = (2·x^3 - 5·x^2 + 8)·(x + 3) = 2·x^4 + x^3 - 15·x^2 + 8·x + 24

The polynomial has ... 5 coefficients ?

The constant of  the polynomial is ... 24

The polynomial has a degree of ... 4

The leading coefficient of the polynomial is ... 2

5 3200sq,ft

80+60+y=180

then divide the difference between 60 and y and add it to 180

so x =180 +( (y-60)/2)

x equals 200

step-by-step explanation:

8

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
