Answer:
96
Step-by-step explanation:
First, you find the area of RPQ using 1/2×base×height. That is, 1/2×6×8. And the answer is 24. Then you multiply 24 by 4 to get the area of all the sides excluding the base to get 96.
This formula solve by discriminant (D=b^2-4ac)
Answer:
B and D
Step-by-step explanation:
Answer:
a. 60/61
Step-by-step explanation:
