Answer:

\large\boxed{9x^3-8x^2}

Step-by-step explanation:

(7x^3-4x^2) + (2x^3-4x^2)\\\\=7x^3-4x^2+2x^3-4x^2\\\\\text{combine like terms}\\\\=(7x^3+2x^3)+(-4x^2-4x^2)\\\\=9x^3-8x^2

Answer:

9x^3 - 8x^2

Step-by-step explanation:

Let's simplify step-by-step.

7x^3−4x^2+2x^3−4x^2

=7x^3+−4x^2+2x^3+−4x^2

Combine Like Terms:

=7x^3+−4x^2+2x^3+−4x^2

=(7x^3+2x^3)+(−4x^2+−4x^2)

=9x^3+−8x^2

I hope this helps you ! :))

Map pours 3 2/3 cup of orange juice into measuring cup from a large container then he poured 1 1/4 cups back into the container
Alecsey [184]

Answer:

2 5/12 cups

Step-by-step explanation:

Map pours 3 2/3 cup of orange juice into measuring cup from a large container then he poured 1 1/4 cups back into the container

The amount of juice remaining in the measuring cup is calculated as:

3 2/3 - 1 1/4

= 3 - 1 + ( 2/3 - 1/4)

LCD = Lowest Common Denominator is 12

= 2 + (4 × 2 - 3 × 1/12)

= 2 + (8 - 3/12)

= 2 + 5/12

= 2 5/12 cups

Hence, the amount of juice remaining in the measuring cup = 2 5/12 cups of juice

How to find the measure of angels
Travka [436]
To find the measure<span> of the smallest angle of the triangle, we multiply 4 times 10. So, 4 x 10 = 40. Remember, the sum of the angles of a triangle is 180 degrees. Just take what you are given in a problem and try to </span>determine<span> what will make the final angle add up to 180 degrees.</span>
