V
Work out the greatest possible value of 3x - 2y.
ii) Work out the least possible value of 3x - 2y.
b) Find the value of 5(a - 4b) when a = -7 and b =

answer: it is a.,b.,d.

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
