Are the linear expression 10x+15 and 5(2x+3) equivalency?

The expressions are equivalent

Step-by-step explanation:

5(2x+3)

Distribute the 5

5*2x + 5*3

10x +15

That is equal to 10x+15  

The expressions are equivalent

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
