D) 2.1+2x=7.5
All the sides added together will equal the perimeter
I believe the answer would be B, since both situations give you 6 chances at drawing/rolling the right number/marble.
Where are the answers?
Step-by-step explanation:
9: B right
10: C obtuse
11: B right
12: B right
I hope they are right! Sorry if they are not!
D. (x-14)(x+14)
a negative and a positive multiplied makes a negative outcome so -14•+14=-196. x•x is = to x^2
