Question 21
What is the area of the parallelogram and triangles?

Enter numbers in the boxes.

First Question: 75 x and 7.5 x

Second Question:

A = bh (parallelogram)

A = 1/2bh (triangles)

Step-by-step explanation:

First Question: It's multiplied by because 75,000 has 3 zeros.

It's also multiplied by because you move the decimal place 4 times on the right at 7.5 which leads to 75,000.

Second Question: Well there aren't specific numbers to solve the areas of the parallelogram or triangle, so I gave the formulas instead. "b" stands for base and "h" stands for height

Hope this helped! <3

step-by-step explanation:

we are given a graph for system of inequalities.

in order to write the system of inequalities for the given graph, we need to find the inequality for each of the line separately.

let us find the slope of dotted line first.

taking two coordinates on the graph.

let us say (0,0) and (3,1).

let us find the slope of the line now.

slope of the dotted line would be =.

y-intercept of dotted line is y=0 only.

plugging slope m= and b=0 in slope-intercept form y=mx+b, we get

.

the line is shaded up of that dotted line.

therefore, for shading up we would take greater than inequality symbol > .

and because it's a dotted line we would take only > symbol in place of = sign in above equation of line.

therefore, inequality for dotted line would be

let us take two points (3,1) and (0,4) on the solid line.

slope of the solid line would be =.

for the solid line we have y-intercept b= 4.

plugging slope m= -1 and b=4 in slope-intercept form y=mx+b, we get

y = -1x + 4.

the line is shaded down of that solid line.

therefore, for shading down we would take less than inequality symbol < .

and because it's a solid line we would take ≤ symbol in place of = sign in above equation of line.

therefore, inequality for solid line would be

is should be y = 5x
