The sum of a and b will be the coefficient of the x term of the trinomial. This can be seen below.

(x + a)(x + b)
= x² + bx + ax + ab
= x² + (a+b)x + ab

x is being multiplied by both a and b individually and the products are being added, so sum of a and b appears as the coefficient of x term.

Thus the answer to this question is option C

Mrac [35]
There are 60 minutes in one hour.
Divide 60 minutes by 10 minutes.

You get 6. That means you would need 6 recycled bottles to power a washing machine for one hour (that will be awesome if that were the case).

Have an awesome day! :)

PLEASE HELP ASAP!!! (No links)

Answer:

No it is not a solution

Step-by-step explanation:

To solve this, you should replace your (x,y) with (8,3)- 8 being your x value and 3 being your y value.

So this inequality, your y value is supposed to be bigger than the value of whatever 3x-4 equals.

So, your inequality should be 3>3(8)-4

3*8=24-4=20

So is 3>(greater than)20? No. Which then means that (8,3) is not a solution because it would make the inequality not true.

Hope this helps!

Which shows the correct method for solving the equation below?<br> 1/3 (y-9) =3
lyudmila [28]

Answer:

y=18

Step-by-step explanation:

we have

\frac{1}{3}(y-9)=3

Multiply by 3 both sides

3*(\frac{1}{3}(y-9))=3*3

(y-9)=9

Adds 9 both sides

(y-9)+9=9+9

y=18
