Answer:
21
Step-by-step explanation:
f(x) =x^2 - 6x + 21
f(xl =0
Answer:
substitute 0 for x
f(0) = 0^2 - 6(0) + 21
0. = 0 - 0 + 21
0. = 21
Answer:
By calculating water displacement
Step-by-step explanation:
Because Julio knows the volume of water in the graduated cylinder, by dropping the pebble in, he can record the new volume of both the water and pebble. Subtracting the volume of the water from the volume of both will leave him with the volume of the pebble. This technique is water displacement.
Don’t know sorry I need point
Subtract 17from both sides
32-17=x
Simplify 32-17 to 15
X=15
