The width of a rectangle is 9 in. shorter than its length. The area of the rectangle is 252 in². What is the length of the recta

erastovalidia [21]

Answer:

the length of the rectangle is, 21 in.

Step-by-step explanation:

Area of the rectangle(A) is given by:

$A=lw$ .....[1]

where,

l is the length of the rectangle

w is the width of the rectangle.

As per the statement:

The width of a rectangle is 9 in. shorter than its length.

⇒ $w = l-9$

It is also given that:

The area of the rectangle is 252 in².

⇒A = 252 in².

Substitute in [1] we have;

$252 = l(l-9)$

⇒ $252 = l^2-9l$

⇒ $l^2-9l -252 = 0$

Factorize this equation:

Split the middle term;

⇒ $l^2-21l+12l-252=0$

⇒ $l(l-21)+12(l-21)=0$

⇒ $(l-21)(l+12)=0$

By zero product property we have;

$l-21 =0$ and $l+12 =0$

⇒ $l = 21$ and $l = -12$

Since, length cannot be in negative

⇒ $l = 21 in.$

Therefore, the length of the rectangle is, 21 inches.

What is an equation of the line that passes through the point (2,-3) and is perpendicular to the line 2x+5y=10?

soldier1979 [14.2K]

Answer:

An equation of the line that passes through the point (2,-3) and is perpendicular to the line is:

$y=\frac{5}{2}x-8$

Step-by-step explanation:

The slope-intercept form of the line equation

$y = mx+b$

where m is the slope and b is the y-intercept

Given the line

$y=-\frac{2}{5}x+2$

Here, the slope = m = -2/5

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

slope = m = -2/5

perpendicular slope = – 1/m = -1/(-2/5) = 5/2

Using the point-slope form of the line equation

$y-y_1=m\left(x-x_1\right)$

where m is the slope and (x₁, y₁) is the point

substituting the values m = 5/2 and the point (2,-3)

$y-\left(-3\right)=\frac{5}{2}\left(x-2\right)$

$y+3=\frac{5}{2}\left(x-2\right)$

subtract 3 from both sides

$y+3-3=\frac{5}{2}\left(x-2\right)-3$

$y=\frac{5}{2}x-8$

Therefore, an equation of the line that passes through the point (2,-3) and is perpendicular to the line is:

$y=\frac{5}{2}x-8$
