Simplify the sum. (7u3 + 4u2 + 7) + (7u3 – 6u + 4)
andreyandreev [35.5K]

Answer:

14u^{3}+4u^{2}-6u+11


Step-by-step explanation:

The question is to simplify  (7u^{3}+4u^{2}+7)+(7u^{3}-6u+4)

<em>We combine like terms, as in, combine cubes with cubes, squares with squares, numbers with numbers and so on.</em>

  • There are 2 cubed terms, so they should be combined.
  • There are 2 numbers, so they should be combined.
  • Others, leave as is.

So we have:

(7u^{3}+4u^{2}+7)+(7u^{3}-6u+4)\\(7u^3+7u^{3})+4u^{2}-6u+(7+4)\\14u^{3}+4u^{2}-6u+11

This is the simplified form of the sum given.

5. Two vertices of a rectangle are (8,-5) and (8,7). If the area of the rectangle is 72 square units, name the possible location
Phantasy [73]

Answer:

<h3>#5</h3>

<u>Given vertices:</u>

  • (8, -5) and (8, 7)

These have same x-coordinate, so when connected form a vertical segment.

<u>The length of the segment is:</u>

  • 7 - (-5) = 12 units

The area of the rectangle is 72 square units, so the horizontal segment has the length of:

  • 72/12 = 6 units

<u>Possible location of the remaining vertices (to the left from the given):</u>

  • (8 - 6, -5) = (2, -5)

and

  • (8 - 6, 7) = (2, 7)
<h3>#6</h3>

<u>Similarly to previous exercise:</u>

  • (5, -8) and (5, 4) given with the area of 48 square units

<u>The distance between the given vertices:</u>

  • 4 - (-8) = 12 units

<u>The other side length is:</u>

  • 48/12 = 4 units

<u>Possible location of the other vertices (to the right from the given):</u>

  • (5 + 4, -8) = (9, -8)

and

  • (5 + 4, 4) = (9, 4)
