The product of a + 3 and –2a2 + 15a + 6 is –2a3 + xa2 + 51a + 18. What is the value of x? a. 3 b. 9 c. 12 d. 15

9

Further explanation

Given:

The product of \boxed{ \ a + 3 \ and \ -2a^2 + 15a + 6 \ is \ -2a^3 + xa^2 + 51a + 18. \ }

Question:

What is the value of x?

Problem solving:

We will solve the case about the distributive property of multiplication.

Let's rewrite and arrange the multiplication equation as follows.

\boxed{ \ (a + 3)(-2a^2 + 15a + 6) = -2a^3 + xa^2 + 51a + 18. \ }

Work out the multiplication of terms carefully.

\boxed{ \ a(-2a^2 + 15a + 6) + 3(-2a^2 + 15a + 6) = -2a^3 + xa^2 + 51a + 18. \ }

\boxed{ \ -2a^3 + 15a^2 + 6a -6a^2 + 45a + 18 = -2a^3 + xa^2 + 51a + 18. \ }

\boxed{ \ -2a^3 + 9a^2 + 51a + 18 = -2a^3 + xa^2 + 51a + 18. \ }

Note the coefficient of the term a² on the left-hand side. Let us equate with a similar term on the right side.

\boxed{ \ 9a^2 = xa^2 \ }

Let us cross out a².

Hence, the value of x is 9.

Ron Co. sold sweatshirts ($20) and baseball caps ($10). If total sales were $2,860 and people bought 6 times as many sweatshirts as caps, how many of each were sold?

Let the total number of sweatshirts sold be S and the total number of baseball caps sold be B
Total sales is the total number of sweatshirts sold times $20 plus the total number of baseball caps sold times 10. 
Equation 1: 20S + 10B = 2860
people bought 6 times as many sweatshirts as caps. Which means the number of sweatshirts sold (S) is 6 times caps sold(B) 
Equation 2:  S = 6B --- substitute S in equation 1 with 6B
=> 20(6B) + 10B = 2860
=> 120B + 10B = 2860
=> 130B = 2860 --- divide both side by 130 
=> B = 2860/130 
=> B = 22 --- is the number of caps sold. 
To find the number of sweatshirts sold we use equation 2
S = 6B --- but we know now B = 22
=> S = 6(22) 
=> S = 132 

therefore 132 sweatshirts sold and 22 baseball caps sold.

4,-24,144,-864,... whats the 8th term in the sequence?

Are 24 and 864 supposed to be negatives?

If so, that means that each term is multiplied by negative 6.
So, 4 times -6 = -24. Then -24 x -6 = 144. And so on.

So -864 x -6 = 5,184. (5th term)
5,184 x -6 = -31,104. (6th term)
-31,104 x -6 = 186,624. (7th term)
186,624 x -6 = -1,119,744. (8th term)

I think, and hope, that it is correct. Hope this helps! :)

The product of two positive numbers is 120. One number is 7 more than the other. Determine the two numbers

Xy= 120
x= 7+y

(7+y)(y) = 120
y^2 + 7y - 120 = 0
(y + 15) (y - 8) = 0

Since we are finding two positive numbers,
If y= 8 then x= 15

The two numbers are 8 and 15
