First you need to calculate how many student is good at math, and that is by knowing how many student forms the 72% of the class total number.
This is by multiplying the total number of the students by the percentage that are good at math.
25* \frac{72}{100} =18
So 18 students are good at math.
So the rest, which are not good at math, are equal to;
25-18=7
The answer is 7.
Hope this helps!

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))
