Simplify 3x + 1x + 5 - 1

4(x + 1)

Step-by-step explanation:

The first step to simplifying this expression would be combining like terms:

3x + 1x + 5 - 1 = (3 + 1)x + 4 = 4x + 4

Now from here, it is possible to simplify this expression further. 4x and 4 both have a factor of 4, so we can factor out 4 like this:

4x + 4 = 4(x + 1)

And now we have simplified the expression.

I hope you find my answer and explanation helpful. Happy studying. :)

triangle and cube

step-by-step explanation:

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
