The perimeter of a rectangle is 32
centimeters. the width is 7 centimeters.

9cm

Step-by-step explanation:

Perimeter of a rectangle = 2(length + width)

Perimeter = 32cm; Width = 7cm

Thus length =

32cm = 2( L + 7cm)

Expanding the bracket

32cm = 2l + 14cm

Collect like terms

32cm - 14cm = 2l

18cm = 2l

Divide through by 2

18cm/2 =2l/2

9cm = l

Therefore, L = 9cm

To check,

Perimeter = 2(l + b)

32cm = 2(9cm +7cm)

32cm = 2(16cm)

32cm = 2 x 16cm

32cm = 32cm

answer is:

1.75 pounds

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
