Answer:
9.6p + 0.4q + 2.2r meters (answer A)
Step-by-step explanation:
We sum up the three side lengths to obtain the perimeter of the triangle:
(6.2p + 4.5q) meters, , and (2.9r – 4.1q) meters
+ (3.4p – 0.7r) meters
+ (2.9r – 4.1q) meters
---------------------------------
9.6p + 0.4q + 2.2r meters (answer A)
Answer: The last one 15
+15g
Step-by-step explanation:
The last one , is not equivalent because after simplifying the expression, you will get 15g^2 + 45g and the last one doesn't match to it.
[3(3)-4][2^2]
=20
The answer is 20.
