We actually need the choices but oh well, we can simpify and hopefuly it is one of the choices
remember the distributive property
a(b+c)=ab+ac
so
7(p+2n)+n
distribute first
7(p)+7(2n)+n
7p+14n+n
7p+15n is an equivilent expression
Answer:

Step-by-step explanation:
Simplify the expression and you will get this.
hope this helps
The height of the fence is irrelevant. The bottom of the ladder is 3+8 = 11 feet from the building. The window is 14ft above the ground:
sqrt(14^2+11^2) = length of your ladder.
Quotient=19
remainder= 3
or
mixed number = 3/35
Uh i dont know are you supposed to add or substract multiply or divid use nixed numbers on no mixed numbers
