X^2+10x+21/x+3?  If you meant (<span>x^2+10x+21)/(x+3), please note that those parentheses are essential.

If you wish to divide </span><span>x^2+10x+21 by (x+3) using synth. div., use the divisor -3:
 
                                        _______________
                                   -3 /    1      10      21  
                                                     -3      -21
                                         -----------------------
                                              1       7        0

Since the remainder is 0, (x+3) is a divisor of </span><span>x^2+10x+21, and the other factor is (1x + 7).</span><span>

A rectangle has a length 3x + 1 of and a width of Write an expression for the 3-9
jolli1 [7]

The expression for the perimeter is P = 12x - 16

<h3>How to write an expression for the perimeter?</h3>

The given parameters are

Length = 3x + 1

Width = 3x - 9

The perimeter is calculated as

P = 2 * (Width + Length)

So, we have

P = 2 * (3x + 1 + 3x - 9)

Evaluate

P = 2* (6x - 8)

Expand

P = 12x - 16

Hence, the expression for the perimeter is P = 12x - 16

(3h-2m)(2h+m) multiple
den301095 [7]
If you want to multiply 2 binomials, take each term in the first set of parentheses and multiply it to every term in the second set of parentheses:
3h*(2h+m) = 3h^2+3hm
-2m*(2h+m) = -4hm-2m^2
Combine like terms: (3hm-4hm)
3h^2-hm-2m^2

Solve for X: -3 |2x+6| = -12
Kobotan [32]
Hello there!

-3| 2x + 6| = -12
2x + 6 = -12/-3
2x + 6 = 4
Solve absolute value
We know that 2x + 6 = 4 or 2x + 6 = -4
We have two possibilities to solve this.

1)
2x + 6 = 4
2x = 4 - 6
2x = -2
Divide both sides by -2
2x/-2 = -2/-2
x = 1


2) 
2x + 6 = -4
2x = -4 - 6
2x = -10
Divide both sides by 2
2x/2 = -10/2
x = -5

Answer : X = -1 or X = -5

A+ Guaranteed!
