C (I think, I don't know for sure but i'm 99.93% sure!)
Answer:
6
Step-by-step explanation:
2(2y - 12) = 0
distribute the 2
2·2y - 2·12 = 0
4y - 24 = 0
add 24 to both sides
4y - 24 + 24 = 0 + 24
4y = 24
divide both sides by 4
(4y)/4 = 24/4
y = 6
Answer:
yes , because X=1 is the only real solutions
Answer:
<em>128</em>
Step-by-step explanation:
<em>Method A.</em>
The volume of the prism is 2 cubic units.
Each cube has side length of 1/4 unit.
The volume of each cube is (1/4)^3 cubic unit.
The volume of each cube is 1/64 cubic unit.
To find the number of cubes that fit in the prism, we divide the volume of the prism by the volume of one cube.
(2 cubic units)/(1/64 cubic units) =
= 2/(1/64)
= 2 * 64
= 128
<em>Method B.</em>
Imagine that the prism has side lengths 1 unit, 1 unit, and 2 units (which does result in a 2 cubic unit volume.) Since each cube has side length 1/4 unit, then you can fit 4 cubes by 4 cubes by 8 cubes in the prism. Then the number of cubes is: 4 * 4 * 8 = 128
Answer:
c) 120
Step-by-step explanation:
f(x) = 7x^4 + 3x^2 - 4
f(-2) = 7(-2)^4 + 3(-2)^2 - 4 = 7(16) + 3(4) - 4 = 112 + 12 - 4 = 120
