m ∠2 = m∠7 Transitive ∠2 = ∠3; ∠3 = ∠7; ∴∠2 = ∠7
Answer:
The answer to your question is x = 30; y = 14
Step-by-step explanation:
Data
JK = x PR = 20
JL = 21 PQ = y
LK = 18 QR = 12
Process
1.- Find x
Use proportions to find it
JK/PR = LK/QR
Substitution
x/20 = 18/12
Solve for x
x = 20(18/12)
x = 360/12
x = 30
2.- Find y
PQ/JL = PR/JK
Substitution
y/21 = 20/30
Solve for y
y = 21(20/30)
y = 420/30
y = 14

(2x^2+6x-11)-(5x^2-x+7)
Pretend that there is a -1 in front of the second bracket
-1(5x^2-x+7)=-5x^2+x-7
2x^2+6x-11-5x^2+x-7
2x^2-5x^2+6x+x-11-7 ( combine like terms)\
-3x^2+7x-18
Answer: d. -3x^2+7x-18
