Marcie wants to enclose her yard with a fence. Her yard is in the shape of a rectangle attached to a triangle. The formula for the area of the enclosed space is A=lw+0.5bh. Solve for b

b = (A - lw) / 0.5h

Step-by-step explanation:

The formula for area of the enclosed place is

A=lw+0.5bh

Where,

A= Area of the enclosed space

l= length of the rectangle

w= width of the rectangle

b= base of the triangle

h= height of the triangle

A=lw+0.5bh

Solve for b

A=lw+0.5bh

Subtract lw from both sides

A - lw = lw + 0.5bh - lw

A - lw = 0.5bh

Divide both sides by 0.5h

(A - lw) / 0.5h = (0.5bh) / 0.5h

(A - lw) / 0.5h = b

Therefore,

b = (A - lw) / 0.5h

step-by-step explanation:

0

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
