C = 9

Step by step:

7(c - 12) = -21

We divide both sides of the equation by 7

C - 12 = -3

The we move the constant, - 12, to the right hand side and change its sign.

C = -3 + 12

Then we calculate the sum

C = 9

A rectangle has a width that is 5 feet less than the length. The area of the rectangle is 126 square feet. Find the dimensions o

mr_godi [17]

Given:

A rectangle has a width that is 5 feet less than the length. The area of the rectangle is 126 square feet

$\\$

❍Let's assume, Length of rectangle x feet and width of the rectangle x - 5 feet respectively.

$\\$

To calculate the dimensions of the rectangle we will use the formula of Area of rectangle:

$\\$

$\: \: \: \: \: \: \: { \underline{ \boxed{ \pmb{ \frak{ Area_{(rectangle)} = Length \times width }}}}} \\ \\$

$\\$

$\underline {\sf{Substituting \: the \: values~ in~ above~formula: }} \\$

$\\$

$: \implies \sf \:x \times (x - 5) = 126 \\ \\ \\ : \implies \sf \:x^2 - 5x = 126 \\ \\ \\ : \implies \sf \:x^2 - 5x - 126 = 0 \\ \\ \\ : \implies \sf \:x^2 - 14x - 9x - 126 = 0 \\ \\ \\ : \implies \sf \:x (x - 14) - 9 (x + 14) = 0 \\ \\ \\ : \implies \sf \:(x - 14)(x - 9) = 0 \\ \\ \\ : \implies { \boxed { \purple{\pmb { \: x = 14 \: \: or \: \: x = -9}}} } \\ \\ \\$

We know that side can't be negative. So, x = 14 feet

Hence,

Width of rectangle = x - 5 = 9 feet
Length of rectangle = x = 14 feet

$\\$

$\\ { \underline{ \pmb{ \frak{\therefore Dimensions \: of \: rectangle \: are \: 9~ feet \: and \: 14 ~feet \: }}}}$
