EX) (x+10)+(3x-5)+x=180

2)Combine like terms.

EX) (5x+5)=180

3) Subtract 5 to both sides

EX) 5x=175

Write an equation for each line.
Tems11 [23]

Answer:

Step-by-step explanation:

Equation of blue line:

blue line is parallel to y-axis

⇒ x = 5

Equation of green line:

Green line is parallel to x-axis.

y = 2

Equation of red line:

At y-intercept x = 0. Point on red line is (0,5)

So, y-intercept = 5

y = mx + b Here,  m is slope any b is y-intercept.

y = mx + 5

Now, choose any other point in red line. ((1,7)

Substitute this value in the above equation and we can find m

7 = m*1 + 5

7 - 5 = m

m = 2

y = 2x + 5

Equation of black line:

Black line and red line are parallel and so, they have same slope.

y = 2x + b

y-intercept (0,-6) ; b = -6

y = 2x - 6

Quadrilateral math is a parallelogram. the area of math is _____.
Semmy [17]
The area of a parallelogram can be obtained by multiplying the length of the base by the height. Although no diagram is given, let us assume values of the base and height that would yield one of the choices as answers. Let us say that parallelogram MATH has the following values:

base = 6 m
height = 11 m

Area = base * height = 6 * 11
Area = 66 m^2

Therefore, the answer is B.
