PLS HELP In the figure below MNO = PQR. Determine the lengh of QR.

A) 14
B) 9
C) 12
D) 3

C) 12

Step-by-step explanation:

Since triangles MNO and PQR are congruent to each other, then their respective line segments are congruent to each other as well.

So since MO is congruent to PR, we can solve for y:

2y+3=21

2y=18

y=9

Also, since MN is congruent to PQ, we can solve for x:

10=4x-2

12=4x

3=x

x=3

QR is the sum of x and y, so the sum would be 3+9=12, therefore, the length of QR is C) 12

step-by-step explanation:

“a term can be a signed number, a variable, or a constant multiplied by a + sign or j sign. in , the terms are 5x , 3y and 8. when a term is made up of a constant multiplied by a variable or variables, that constant is called a coefficient.” i hope this you.
