A rectangle width is one fourth it’s length, outs are is 9 square units. The equation I(1/4I)=9 can be used to find I, the lengt
OlgaM077 [116]

Answer:

The length of rectangle is 6 units and the width is 1.5 units

Step-by-step explanation:

Let

L -----> the length of rectangle

W ----> the width of rectangle

we know that

The area of rectangle is equal to

A=LW

we have

A=9\ units^{2}

so

9=LW -----> equation A

A rectangle width is one fourth it’s length

so

W=\frac{1}{4}L ----> equation B

substitute equation B in equation A and solve for L

9=L(\frac{1}{4}L)

L^{2}=9*4

L^{2}=36

take square root both sides

L=6\ units

Find the value of W

W=\frac{1}{4}(6)

W=1.5\ units

love history [14]

y=-x

slope for perp line = 1

2y=-x+6

y=-1/2x +3

slope for perp line = 2

15.

i don’t wanna do all sorry it’s a lot of work so i’ll tell u how to do it instead. first write it in slope intercept form which is

y-y1=m(x-x1)

it’s parallel which means it shares the same slope. if it’s perpendicular it would be opposite reciprocals so for -3/2 the perp slope would be 2/3.

the line is

y+1=3/4(x-4)

we distribute the 3/4 so it’s now

y+1=3/4x-3

then we subtract the 1

y=3/4x-4 is the equation boom done
