Answer:2y^2-6y+6
Step-by-step explanation:
5y^2-2y+1-(3y^2+4y-5)
5y^2-2y+1-3y^2-4y+5
Collect like terms
5y^2-3y^2-2y-4y+1+5
2y^2-6y+6
It’s c I just did that hope it help
(x^-3)^ -5x^6=x^(-3· -5x^6)=x^15x^6
Answer:
B.) 191.1 cubic cm.
Step-by-step explanation:
First find the area of the rectangular prism. Because the formula is l * w * h, this becomes 
= 149.1.
For the volume of a pyramid, the equation is 
. We already know the height, and because it's sitting on top of the rectangular prism, the base should have the same area. In other words, if the prism has a base of 7*6, then the pyramid can be found through 
. 7 Multiplied by 6 is 42, and since it's multiplied but also divided by 3, they cancel out, leaving only 42.
The sum of both of these shapes is 191.1 cm³.
