Answer in Algebra
The correct expression for a number which is 9 times as big as the number obtained after p has been increased
by 4, is
9(p + 4)
One of the unknown variable is p.
First of all, we know that the number is 9 times as big (multiplication) as the new number obtained through the addition of four to p i.e (p + 4).
Translating the word problem into an algebraic expression, we have;
9 ×(p + 4) = 9(p + 4)
Simplifying further, we have;
9p + 36
