Answer:

52

Step-by-step explanation:

12-3n=-7n-4(n+5)

Step 1: distribute

12-3n=-7n-4n-20

Step 2: Combine like terms

12-3n=-11n-20

Step 3: Move N to one side

12-3n=-11n-20

  +11n +11n

12+8n=-20

Step 4: Get normal numbers to the other side

12+8n=-20

-12         -12

8n=-32

Step 5: Take away the number infront of N by dividing each side by the number of Ns

8n=-32

/8     /8

n= -4

Step 6: Plug N into: 32-5n

32-5(-4)

Step 7: Get rid of parenthesis by multiplying. Negative times Negative is positive.

32+20

Step 8: Finish the problem

Answer is 52

Rafeal wants to know if there is a single transformation that will move trapezoid JKLM onto trapezoid PQRS Below
aliina [53]

A. A 90° counterclockwise rotation of trapezoid JKLM about the origin will move angle L onto angle R.

Step-by-step explanation:

Since both the trapezoids, trapezoid JKLM and PQRS are congruent, we can do any transformation, may be rotation, reflection and translation.

A 90° counterclockwise rotation of trapezoid JKLM about the origin will move angle L onto angle R is the true statement others are incorrect statements.

When the Preimage is rotated 90° counterclockwise rotation, then its coordinates (x,y) changed into (-y,x)

Calculate the area and the perimeter of the figure​
Otrada [13]

Answer:

Area: 5 cm squared

Perimeter: 12 cm

Step-by-step explanation:

The area is Length times Width, and there is 5 different sqaures in the figure.Each sqaure has an area of 1 by 1, which is 1. 1 times 5 is 5. So the area is 5. You can get the perimeter by adding all the side lengths together, 2+3+2+1+1+1+1+1=12. The perimeter is 12. Hope this helps.
