Answer:

42

Step-by-step explanation:

First find the area of the rectangle as though all of it was shaded.

That means that the length is 7 + 7 = 14

The width does not change and it is 4

The total area is 14 * 4 = 56 square units.

Now find the area of the right triangle.

Area rt triangle = 1/2 b * h

b = 4

h = 7

Area rt triangle = 4 * 7 / 2 = 14

You want the are of everything but the the right triangle.

Area shaded part = Total area - area right triangle = 56 - 14 = 42

A new club sent out 231 coupons to boost sales for next year's memberships. They provided 6 times as many to potential members t
grin007 [14]

Answer:

Number of coupons sent  to Existing members = 33

Step-by-step explanation:

Number of coupons sent out = 231

Let :

6 times as many to potential members = 6 * X = 6X

while existing members = X

therefore 6X + X = 231

                 7X = 231

therefore  X = 231 / 7 = 33

so existing members = 33

while potential members = 6 * 33 = 198

PLEASE HELP !!!! ILL GIVE BRAINLIEST !!!
Marta_Voda [28]

Answer:

Hi it's down below! Hope it helps

Step-by-step explanation:

1) The angles are Supplementary

This is because both angles form 180°. The angle below angle "7x+9" is the same as 5x+3.  The angle above angle"5x+3" is the same as 7x+9.

2) They are both supplementary

They form 180°

3)180° = 12x+12°

4) Solving that:

180° - 12° = 12x

168° = 12x

x = 168°/12

x = 14°

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!
