3x = -2y
or 3x + 2y = 0
it is the standard form.
Cube A volume = 3^3 = 27 cubic meters
Cube B volume = 6^6 = 216 cubic meters
Cube B has (216 / 27) the volume (or 8 times the volume) of Cube A.
Answer:
f(-3) = 16
Step-by-step explanation:
Given:
f(x) = 2x² + x + 1
Required:
f(-3)
Solution:
Substitute x = -3 into f(x) = 2x² + x + 1
f(-3) = 2(-3)² + (-3) + 1
f(-3) = 2*9 - 3 + 1
f(-3) = 18 - 3 + 1
f(-3) = 16
Answer -4/27
-1/9 x 4/3 will give you -4/27
