The answer is 4.
The reason is that 5 times 4 is 20.
Answer:
0
Step-by-step explanation:
Use the values of a
, b
, and c to find the discriminant.
6x-2x^2 would be the answer
Answer:
254.5 in.^2
Step-by-step explanation:
diameter of mirror = 12 in.
radius of mirror = diameter/2 = 13 in. / 2 = 6 in.
frame width = 3 in.
radius if combined mirror and frame = 6 in. + 3 in. = 9 in.
A = (pi)(r^2)
A = 3.14159 * (9 in.)^2
A = 3.14159 * 81 in.^2
A = 254.5 in.^2
