Answer:
D: 850 cm^3
Step-by-step explanation:
You sum the volumes.
Prism is 15*5*7 = 525
Pyramid is 15*5*13/3 = 325
Sum is 850
-0.5(3x + 5) and -1.5x + 2.5
-0.5(3x + 5)...distribute the -0.5 thru the parenthesis
-1.5x - 2.5
no, these are not equivalent.... one is -1.5x + 2.5 and the other is -1.5x - 2.5....not the same
