What is five×fivewhat is the answer for 4 x 5
Mandarinka [93]
Well 
<span>
4 x 5 = 20 

and

5 x 5 = 25

I'm sure a calculator could help you out with this, But if you don't have access to a calculator I'll show you how to multiply. It's just like adding, Let's use 6 x 7 for example. Take the first number ( Which is 6 in this case ) and look at the second number ( Which would be 7 ) The second number represents how many times you would add the first number together. So:

6 + 6 + 6 + 6 + 6 + 6 + 6 = 42 ( We add 6 together 7 times )

So

6 x 7 = 42

There are faster methods but this is probably the best way to start out.

MaRussiya [10]

Answer:

x > - 3

Step-by-step explanation:

Given

3(x + 2) > x  ← distribute left side

3x + 6 > x ( subtract x from both sides )

2x + 6 > 0 ( subtract 6 from both sides )

2x > - 6 ( divide both sides by 2 )

x > - 3
