No
Step-by-step explanation:
A^2+b^2=c^2
8^2+15^2=20^2
64+225=400

Answer:
X>1
Step-by-step explanation:
-4 (x - 5) + 3 (a - 7)
First, expand your problem. / Your problem should look like: -4x + 20 + 3a - 21
Second, simplify. / Your problem should look like: -4x + 3a - 1
Answer: -4x + 3a - 1 (C)
Answer:
Step-by-step explanation:
