The correct expression for a number which is 9 times as big as the number obtained after p has been increased

defon

Answer:

9(p + 4)

Step-by-step explanation:

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

Solve this please with steps b^4-3b^3-10b^2

gtnhenbr [62]

Answer:

Step-by-step explanation:

There's no "solving" to be done because its an expression, but im assuming the question wants you to factor.

$b^4-3b^3-10b^2$

First, factor out a b^2

$b^2(b^2-3b-10)$

Factor the trinomial. What two numbers multiply to equal -10 but add to equal -3? They are -5 and +2

$b^2((b-5)(b+2))$
