Plan A: 30 + 0.01m
Plan B: 20 + 0.05m
in order for 2 plans cost the same, both need to be equal
so should be
20 + 0.05m = 30 + 0.01m
answer is D. last one
20 + 0.05m = 30 + 0.01m
Answer:
Step-by-step explanation:
A group of students is arranging squares into layers to create a project.
- The first layer has 4 squares.
- The second layer has 8 squares.
- The third layer has 12 squares.
- And so on
You can see that each next layer has 4 more squares than previous one. Hence, for n>0
Answer:
1. y = 9(x+1/2)^2 -13/4
Step-by-step explanation:
y = 9x^2 + 9x – 1
first isolate the x terms
y = 9(x^2 +x) -1
then add 1/4 inside the brackets to make it a perfect square trinomial (half of the coefficient of the x term squared is how we get 1/4)
since we just added 1/4 we need to subtract what we just added to balance the equation. so 1/4 times 9 is 9/4 ( the number we just added to the equation). then you subtract 9/4 outside of the brackets.
y = 9(x^2 +x +1/4) -1 -9/4
then simplify
y = 9(x+1/2)^2 -13/4
So what u do is multiply let me attach something
Answer:
The factorization of is
Step-by-step explanation:
The problem is a <em>sum of cubes factorization</em>, this type of factorization applies only in binomials of the form which means numbers that have exact cubic root and the exponents of the letters a and b are multiples of three.
Sum of cubes equation
So, let's factor
we have to bring the equation to the form
con y
Solving using sum of cubes equation
