Positive × Positive = Positive
3 × 2 = 6
m × n = mn

Positive × Negative = Negative
8 × -4 = -32
m × -n = -mn

Negative × Negative = Positive
-5 × -4 = 20
-m × -n = mn
(-x) × (-x) = x²

The same rules apply for division as multiplication.

A rectangular prism with a volume of 3 cubic units is filled with cubes with side lengths of 1/4 unit how many 1/4 unit cubes do
Julli [10]

Answer:

192 cubes

Step-by-step explanation:

So all we need to do is:

1) Find the area of 1 cube.

2) Divide the large prism volume with this.

SO 1)

the volume of cube = Length * width * height = (1/4)^3 = 1/64

SO 2)

the volume of prism / the volume of cube = 3/(1/64) = 192

Answer: 192 cubes

I need help asap<br> if F(4)=9, the corresponding ordered pair is what
vaieri [72.5K]

Answer:

F(5)=11.25

Step-by-step explanation:

I'm like 80% sure this is right, and I hope it helps.

First I did 9/4 which equals 2.25. and that would be F(1)

then added 2.25 to 9 which equals 11.25

multiplying 2.25 by 5 would also equal 11.25.

I did 5 because, on a number line, 5 comes after 4.
