It would be 3.14(7)^2
Then 3.14*49
Multiply those two to get your area
It’s D.) 2n-8 hope this helps
It is 74 degrees because those two equations equal each other and you must cancel them out which equals x=15. plug 15 in to one of the equations and you have the answer.
Answer:
c^3 + c^2 - 7c + 20
Step-by-step explanation:
First, expand the expression using distributive property.
c^2(c+4) - 3c(c+4) + 5(c+4)
c^3 + 4c^2 - 3c^2 - 12c + 5c + 20
Lastly, simplify like terms.
c^3 + c^2 - 7c + 20
