Answer:
1.5 inches/ week
Step-by-step explanation
Given
Height of he plant = 3in
If the plant grows by 2in every week
The rate of change = Height of plant/weekly increase
The rate of change = 3/2 = 1.5 inches/ week
Answer would be b
(5x-7)(2x-3)=10x^2-15x-14x+21=10x^2-29x+21
Answer:
Step-by-step explanation:
For APEX the correct answer is $1,200.00
72,000/12= 6,000
6,000x .2= 1,200
Answer:
2(2x+1)(4x−3)
Step-by-step explanation:
GCF = 2
2( 16x^ 2/ 2+−4x/2− 6/2)
2(8x ^2−2x−3)
2(8x ^2 +4x−6x−3)
2(4x(2x+1)−3(2x+1))
2(2x+1)(4x−3)
Pull an x from the first two terms
x(x^3 + y^3) + (x^3 + y^3) Now x^3 + y^3 is a common factor.
(x^3 + y^3)*(x + 1) That should be far enough. It can be factored further by factoring (x^3 + y^3) but there is no point because you can't do anything after that. But in case you want to know how x^3 + y^3 factors
(x^3 + y^3) = (x + y)(x^2 - xy + y^2)
Which means you could write original polynomial as
(x + y)(x^2 - xy + y^2)(x + 1)
Part B
You factored the x out of xy^3 so that you would have a common factor (x^3 + y^3) to pull out as a common factor for the whole polynomial.
