Plssss help 30 pointsss<br><br> If your slope is 1/3 how do you move horizontally?
sweet [91]

What is 1/3 as a slope?

The answer is approximately 18.43º. A slope of 1 in 3 means the slope is 1/3. It also means a rise of 1 and a run of 3. On a graph, starting at the origin, go up 1 unit, then from there, go to the right 3 units.

(hope this helps) :)

I need help with three and four
mart [117]

Answer:

3: a^{2}+2ab+b^{2}

4: 8x^{3} -12x^{2}+6x-1

Step-by-step explanation:

Question 3 can be re-written as:

(a+b)(a+b)

which equals:

a^{2}+2ab+b^{2}

Question 4 can be re-written as:

(2x-1)(2x-1)(2x-1)

Doing the first 2 brackets gives us:

(4x^{2} -4x+1)(2x-1)

Expanding these two:

8x^{3} -4x^{2} -8x^{2} +4x+2x-1

Simplifying it:

8x^{3} -12x^{2}+6x-1
