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 is the product of the common factors at the lowest exponents.
All three terms are multiples of 3, r, and s.
The lowest exponent of 3 is 1. The lowest exponent of r is 2. The lowest exponent of s is 1.
GCF = 3r²s
Factor from the polynomial.
9r⁵s + 6r⁴s² − 12r²s
3r²s (3r³ + 2r²s − 4)
So what you want to do is multiply 245 by 1.65 (because it’s +65%) and by doing that you get $404.25 :)
Answer:
Step-by-step explanation:
Let denote side of the square base.
Area base=Area top:
#Area of base and top is each
Given the volume as 5 cubic feet and side of base as x, height is:
Substitute the given prices to give the function for cost of material.
Top=30cents/ft, Base=10cents/ft and sides =50cents/ft:
The function for the cost of material is expressed as:
That’s easy. 6000 x 6% = 360 x 20 = 7200
6000 + 7200 = 13200
