Which set of ordered pairs in the form of (x, y) does not represent a function of x? A. {(0, 2), (1, -1), (2, 3), (3,-2)}

B. {0,-2), (1, 1), (2,3), (3,-2)}

C. {(0, 2),(-1,-1), (2, -3), (3, 2)}

D. {(0, 2), (1, 2), (1, -2), (3, 2)}

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

for this case we must apply distributive property to the following expression:

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:
