The perimeter of a rectangle is 250 inches. if the length is 4 times as big as the width, what is the length and width of the re
yarga [219]

The length and width of the rectangle are 7.90 inches and 31.6 inches respectively

It is given that,

Let the length of the rectangle = l

Let the width of the rectangle = w

The perimeter of the rectangle = 250 inches

l x w = 250 ....eq 1

Then,

Length is 4 times as big as width

4l = w

We need to find, the length and width of the rectangle

Putting the value of w in eqn 1

We get,

4l^{2} = 250

l^{2} = 62.5

l = \sqrt{62.5}

l = 7.90

Similarly, we can get,

w = 4l

w = 4 x 7.90

w = 31.6

Hence, the length and width of the rectangle are 7.90 inches and 31.6 inches respectively

Write the equation of the line that is parallel to the line and through the given point y=-2x+1 point (0,5)
marysya [2.9K]

Answer:

y = -2x+5

Step-by-step explanation:

y = -2x+1 is in the form y= mx+b where m is the slope and b is the y intercept

-2 is the slope

Parallel lines have the same slope so our new line will have the same slope

y = -2x+b

The point given is the y intercept (value when x is zero)

b = 5

y = -2x+5
