Which property is illustrated by the expression 5(4+2)=20+10

  distributive property

Step-by-step explanation:

The distributive property tells you ...

  a(b+c) = ab +ac

  5(4+2) = 5·4 +5·2 = 20 +10

the monthly balance will be $75,000

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
