Answer:

(A) 142.5 square inches

Step-by-step explanation:

It is given that A kite with two top triangles with height of 5 inches and a base 7.5 inches. The bottom two triangles share the base but have a height labeled 14 inches that is:

DE=5in, EC=7.5in, EB=14in

Now, area of the two top triangles of the kite=2(\frac{1}{2}{\times}EC{\times}DE)

=EC{\times}DE

=7.5{\times}5

=37.5 square inches

Also, area of the two bottom triangles of the given kite=2(\frac{1}{2}{\times}EC{\times}EB)

=EC{\times}EB

=7.5{\times}14

=105 square inches

Therefore, the total area of the kite=area of the two top triangles of the kite+area of the two bottom triangles of the given kite

=37.5+105

=142.5 square inches.

raketka [301]

Answer:

3

Step-by-step explanation:

2x + 3 = -x + 12

subtract 3 from both sides

2x = - x + 9

add x to both sides

3x = 9
