Which equation is an identity? A. (9x/15) + 27 = (9x/15) + (27/15) B. 3((x/2) + 16) - 16 = (3/2)x C. -4(3 - 2x) = -12 - 8x D. -5((x/15) - 16) - 30 = 50 - (1/3)x E. 36((3/4)x- 2) + 72 =-72 + 27x

43

step-by-step explanation:

363 square inches

step-by-step explanation:

surface area of a pyramid is b + 1/2ph

b is the area of the base: 11 x 11 = 121

p is the perimeter of the base: 11 + 11 + 11 + 11 = 44

h is the height of the pyramid: 11

121 + 1/2(44)(11)

121 + 242

363

answer

a) the midrange of the data set shown is 85.5

step by step explanation

let's find the midrange.

the midrange is nothing but add the greatest value and the least value, then divide it by 2.

here the greatest value = 99

the least value = 72

midrange = (99 + 72)/2

= 171/2

midrange = 85.5
