Answer: 5a + 2b
Step-by-step explanation:
She purchased 12a pounds of apples and she used 7a pounds, so that means 12a - 7a = 5a
She purchased 4b pounds of bananas and used 2b pounds, so that means 4b - 2b = 2b
y^2 +6^2 = 12^2
y^2 +36 = 144
y^2 = 108
sqrt(108) = 10.392 = 6sqrt(3)
Answer is B 6sqrt(3)
Answer is D because you Do 37*5
(6,-9) it is 3 units away from both 3 and 9, and -9 is 2 units away from -7 and -11.
86.5 is the missing angle because a triangle has too add up too 180 degrees add the two angles then subtract by 180 and get 86.5
