From the set {8, 18, 26}, use substitution to determine which value of x makes the inequality true. 4 + x < 22

4 + 8 < 22

Step-by-step explanation:

Take all of the given numbers from the set and add them with 4

4+8=12

4+18=22

4+26=30

Meaning the only answer that is smaller than 22 is 4+8

Four plus eight is less than 22

47.28 or 47.2857143

step-by-step explanation:

you just divide 331 by 7 and you get that answer. ( i think so tho)

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
