Which of the following shows the addition property of equality? a.) 4x/4 = 10/4 x=2.5 b.) 16x-2+2 = 18+2 16x=20 c.) 8x+2x= 10x d.) 4(3x+1)=8 12x+4=8

By definition we have to:

Addition Property of Equality is a property that allows you to add the same number to both sides of the equation. This number is added on both sides in order not to alter the equality.

Therefore, the following equation uses this property:

We note that 2 is added to both sides of equality.

Rewriting we have:

the following shows the Addition Property of Equality

B.) 16x-2 + 2 = 18 + 2

16x = 20

let f (x ) is a function and c be a positive real number,   the graph of the function g (x ) = f (cx ) is represented as follows.

when, c > 1,   the function compresses it in the x - direction.

when, 0 < c < 1, the function stretches it.

the function is g ( x ) = (9x )2.

the heighest power of x in g ( x ) = (9x )2 is 2, so the parent function is square function.

the equation of parent function is f ( x ) = x 2 .

the function is g ( x ) = (9x )2 and the parent function is f ( x ) = x 2 .

so, the functions f and g have the following relationship.

g ( x ) = f ( 9x ).

compare the function g ( x ) = f ( 9x ) with g (x ) = f (cx ).

c = 9 ( > 1 ).

so, the function g (x ) = (9x )2 compresses it in the x - direction.

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
