Answer: C. 78

Step-by-step explanation: Good luck! :D

There are 12 inches in a foot, there are 6 feet. 6 x 12 = 72

1/2 of a foot is 6 inches. 72 + 6 = 78!

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)

(5x2+4xy-7)+(3x2+2xy+3)
Juliette [100K]

Answer:

8x² + 6xy - 4

Step-by-step explanation:

(5x² + 4xy - 7) + (3x² + 2xy + 3) ← remove parenthesis

= 5x² + 4xy - 7 + 3x² + 2xy + 3 ← collect like terms

= 8x² + 6xy - 4

Area of a Triangle = 1/2 * base * Height

2.5 = 1/2 * 2 * h

2.5 = 1 * h

h = 2.5 /1

h = 2.5 in

In short, Your Answer would be: Option C

Hope this helps!
