What is the perimeter of the trapezoid 10 points

19 units

Step-by-step explanation:

There are two sides that are equal; they are 4 units long.

The unequal sides are 7 and 4 in length.

Add up these four sides to obtain the perimeter:

P = 4 + 4 + 4 + 7 = 19 units

The perimeter of a figure is the distance around the figure.

To find the perimeter of the trapezoid shown, we can simply add the sides. Each square represents 1 unit.

Once we count each square that has a line through it, we will get

7 + 4 + 4 + 4 = 19

Therefore, the perimeter of the trapezoid is 19 units.

(0,-3) see attached graph

step-by-step explanation:

a. to solve the system, graph the two equations.

x = y+3 becomes y=x-3 has m=1/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move up 1 unit and 1 unit to the right. plot a point and connect.

y=-4x+3 has m =-4/1 and b=-3. start at (0,-3) on the y-axis and plot a point. then move down four units and to the right 1 unit. plot a point and connect.

the solution is the point (x,y) where the two lines intersect. by the graph below it is (0,-3).

b. to solve by substitution, substitute y = -4x-3 into x= y+3

x= (-4x-3) +3

x=-4x

5x=0

x=0

now substitute x = 0 back in to find y.

y= -4(0)-3

y=0-3

y=-3

solution is (0,-3)

c. use elimination by adding the equations together.

x-y=3

4x+y=-3

5x=0

x=0

then substitute into one equation to find y.

y=-4(0)-3

y=-3
