=(3x2 + 2x + 4) - (x2 + 2x + 1)

Combine like terms

=(3x2-x2)+(2x-2x)+(4-1)

=2x2+0+3

The 2x terms cancel each other to 0

=2x2+3

C) 2x2+3 is the answer.

Hope this helps!

Answer:

15x^2+17x+4

Step-by-step explanation:

(3x+2x+4)(x+2x+1)

Combine 3x and 2x to get 5x.

(5x+4)(x+2x+1)

Combine x and 2x to get 3x.

(5x+4)(3x+1)

Apply the distributive property by multiplying each term of 5x+4 by each term of 3x+1.

15x ^2+5x+12x+4

Combine 5x and 12x to get 17x.

15x^2+17x+4

Answer:

7/3

Step-by-step explanation:

The point at the right end of segment 5 is 7 units above and 3 units to the right of the point at the left end. The slope is the "rise" divided by the "run":

slope = m = rise/run = 7/3

The slope of segment 5 is 7/3.

I need help am I doing this right

disa [49]

No, you got the inequalities the wrong way.
In negative numbers, it is how much lower it is than 0. For example, -22 is 22 less than 0. And -2 is 2 less than 0. Here, -22 is actually less than -2 because it is farther below 0 than -2.
You can understand this better if you graph it on a number line.
So, -12 >-15. (-15 is 3 less than -12).
-1/3 >-1.
-2>-21.
