First answer gets the best marks

Step-by-step explanation:

This is because you have the equation of 2(2/5x + 2).

When you simplify it you have to first do the parenthesis.

So, 2 * 2/5 = 4/5. This is because 2/1 *2/5 is 4/5.

Then you have to do 2*2. This is equal to 4.

Put them together. So it will be.

It's the second answer, im pretty sure.

Step-by-step explanation:

Use the distributive property to distribute 2 into the term in parentheses.

correct answer:

b.(19,-2)

step-by-step explanation:

a cube has 6 sides

the probability of getting 5 on the first cube is 1/6 since only one side of the cube has 5 on it.

there are 3 sides of the cube with even number on it [2,4,6]

therefore the probability of getting even number is 3/6

for both events to happen together, the probability would be

1/6 x 3/6 = 12/36

which simplifies to 1/12
