If presented with the following equation, what is the next step in the equation solving sequence? 3x + 4x = -40 - 21 + 7

The next step is to combine like terms

Step-by-step explanation:

If we are solving for x, we have to isolate x on 1 side and get another number on the other side. To do this, we have to add 3x to 4x to get 7x and add -40, -21, and 7 to get -54.

i will with my problems and all the other things that need to   be on by the way

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
