For this case we must find an expression equivalent to:
By definition of power properties we have to meet:

So, rewriting the expression we have:

Answer:

Answer:
I think it’s c
Step-by-step explanation:
Answer:
b
Step-by-step explanation:
Answer: x=4
Step-by-step explanation:
We know that line segment AC= AB + BC
we also know that AB= 3x+8 and BC= 2x-5
by substituting these, we get AC= (3x+8)+(2x-5)
AC is given as being 23, so we know that
23= (3x+8)+(2x-5)
by combining like terms, we get that
5x+3=23
simplify this to get that x=4
