If x = 4

x² + 2x = 24

Substitute x by its value

4² + 2(4) 
16 + 8 = 24

We simply need to plug in x = 4 into x² + 2x

So plugging in x = 4, we get:

4² + 2(4)

Simplifying it, we get:

16 + 2(4)
16 + 8
24

When x = 4, x² + 2x will equal 24.

What is 67/7 as mixed number
monitta

Answer:

9 4/7

Step-by-step explanation:

First, we need to make as many 7s as possible. If we do 67/7, we will get 9...... so our whole number is 9. If we do 7 x 9, we get 63 and if we subtract 63 from 67, we are left with 4. All in all, we will get 9 4/7!
