The answer is C. To find the average or mean, you add up all the values, then divide by how many values there are. 76+99+86=261. 261/3=87. So, I looked at the options and did the math. 76+99+86+88=349. 349/4=87.25. When I used 90, I got 87.75. When I used 99, i got 90 total. So, C is your answer. Hope I helped!

Use the diagram to determine which statement is true

Dahasolnce [82]

The answer is d.

Finding area of ABCD :

Find side length

side = √3² + 4²
side = 5

2. Apply formula to find area

area = 5²
area = 25

Finding area of GHIA :

area = 4²
area - 16

Finding area of DEFG :

area = 3²
area = 9

Now, let's see whether is true.

Area (ABCD) - Area (GHIA) = Area (DEFG)
25 - 16 = 9
9 = 9

∴ Hence, it is proved √

In kite ABCD, AB = BC and CD = DA. AB = (3x + 4), BC = x + 8, CD = y + 7, and DA = 2y + 5, find the perimeter of the kite

lana [24]

3x + 4 = x+ 8 > 3x - x = 2x > 2x + 4 = 8 > 8 - 4 = 4 > 2x / 2 crosses out > 4 / 2 = 2 > x=2
2y + 5 = y + 7 > 2y - y = y > y+ 5 = 7 > 7-5= 2 > y=2

the perimeter of the kite is 4
