I think that one number is 77 and the other is 86. 77 + 9 is 86. 86 +77 is 163.
Answer:
143
Step-by-step explanation:
x-31=112
Add 31 to both sides,
x - 31 = 112
+31 +31
-31 and +31, cancel out so we're left with...
x = 143
(5x+15)(6x-10)
= 30x^2 + 30x - 50x - 150
= 30x^2 - 20x - 150
64; Line pq is correspondent with line ab and triangle PQR is 4 time as big as triangle ABC.
