Jorge's printer can print 60 pages in 15 minutes. How many pages can it print in 3/4 hours?
satela [25.4K]
60pages per 15 minutes. If you know 3/4 of an hour is 45minutes, then how many times does 15 do into 45? The answer is 3. So multiply the amount of pages by 3. 60x3=180pages

What is the greatest common factor of the polynomial's terms?
Alinara [238K]

Step-by-step explanation:

Write the prime factorization of each term:

9r⁵s = 3² × r⁵ × s

6r⁴s² = 2 × 3 × r⁴ × s²

12r²s = 2² × 3 × r² × s

The greatest common factor will have all the common factors raised to their lowest exponent.

So all three terms have 3, r, and s as factors.  The lowest exponent of 3 is 1.  The lowest exponent of r is 2.  The lowest exponent of s is 1.

GCF = 3 × r² × s

GCF = 3r²s

Factor out the GCF:

9r⁵s + 6r⁴s² − 12r²s

3r²s (3r³ + 2r²s − 4)

5X exponent 2 + 10x- 45=
Slav-nsk [51]
I’ll assume the question is asking us to factor the above polynomial:
5x^2 + 10x - 45

Factor out a 5:
5(x^2 + 2x - 9)

This appears to be an irreducible quadratic polynomial, so let’s leave it alone.
5x^2 + 10x - 45 = 5(x^2 + 2x - 9)
