What is the quotient of (x3 + 6x2 + 11x + 6) ÷ (x2 + 4x + 3)? x + 2 x – 2 x + 10 x + 6

evablogger [386]

Answer:

x + 2

Step-by-step explanation:

If we know one of the factors, we should be able to use long division.

We can divide the trinomial by the binomial and find the other factor.

x + 2

x² + 4x + 3)x³ + 6x² + 11x + 6

x³ + 4x² + 3x

2x² + 8x + 6

2x² + 8x + 6

Thus,

$\dfrac{x^{3} + 6x^2 + 11x + 6} {x^{2} + 4x + 3} = \mathbf{x + 2}$

Find all numbers whose absolute value is 3 . If there is more than one, separate them with commas. If there are no such numbers,

adelina 88 [10]

Answer:

3, and -3

Step-by-step explanation:

Because absolute value is the distance away from zero, |3| and |-3| would both be 3 units away from 0. Be sure to have the negative on the inside if you're trying to make something positive, otherwise -|3| means that the absolute value of 3 would then become negative since the negative sign isn't a part of the absolute. hope this helps!

Sue uses the expression 8x3000+ 8x200+ 8 x 9 to help solve a multiplication problem what is sues multiplication problem

Iteru [2.4K]

we know that

the expression (8x3000+ 8x200+ 8 x 9) is equal to

$8*3,000+ 8*200+ 8 * 9 =8*(3,000+200+9)\\ =8*(3,209)\\ = 25,672$
