INTERMEDIATE ALGEBRA combine like terms to simplify the following expressions 3x + 4x - 5x

I think the answer is 2x

Step-by-step explanation:

2x

Step-by-step explanation:

For this problem, we can tackle it by using the distributive property and factoring.  We are given the following expression:

3x + 4x - 5x

And are told to simplify the expression.  Let's factor out the x from all the terms, and then simply use addition to simplify.  From here we can redistribute the x to gain our simplified expression:

3x + 4x - 5x

= x ( 3 + 4 - 5 )

= x ( 7 - 5 )

= x ( 2 )

= 2x

Hence, the simplification of the expression 3x + 4x - 5x is 2x.

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
