Answer:
Area=210
perimeter=66
Step-by-step explanation:
A=a+b(h)/2
P=a+b+c+d
If the two triangles are congruent, then WX=PQ, because they are corresponding(by the order of the letters WXY and PQR). So if they are congruent, then we can say 5n-2=63, by the transitive property. The rest of the problem only requires Pemdas. Add 2 to both sides (5n=65), divide both sides by 5 (n=13), and you find that n=13.
Answer: 75% off the original price.
Step-by-step explanation:Say an item is $100. 50% off $100 is of coarse $50.
Now 50% off that price is $25.
So the new price is now $25 which is 75% off.
Answer:−2n+6,−2n+6
Step-by-step explanation:
5n+6−7n,5n+6−7n
((5n−7n)+6),((5n−7n)+6)
−2n+6,5n−7n+6
−2n+6,((5n−7n)+6)
−2n+6,−2n+6
