Well, the way I see it is that both Mr. Romano, and Ms. Guerra are correct but Professor McCoy is incorrect because he said (x+2) when it should be (x-2).
The factor theorem states that:
If f(a)=0, then (x-a) is a factor
The remainder theorem states that:
If (x-a) is a factor of f(x), then f(x) / (x-a) = 0
So if 2 is indeed a zero of f(x), then a factor must be (x-2) according to the fist which supports Ms. Guerra and also if (x-2) is indeed a factor as Ms. Guerra says then we know that f(x) / (x-a) = 0 which supports Mr. Romano
Professor McCoy is wrong because he used (x + 2) when it should be (x-2). I know this because according to the factor theorem if f(a)=0, then (x-a) is a factor. And the remainder theorem says if (x-a) is a factor of f(x), then f(x)/x-a =0.
Answer:
2044 cubic inches
Step-by-step explanation:
The amount of concrete required is the larger volume MINUS the smaller volume.
Note: Volume of cube = s^3 where s is the side length
Larger Volume = s^3 = 15^3 = 3375
and
Smaller Volume = s^3 = 11^3 = 1331
Hence, amount of concrete needed to make 1 planter = 3375 - 1331 = 2044 cubic inches
When 2 lines are coinciding, this means its the same line.
One equation is simply a multiple of the other.
8x = 4x*2
This means the multiplier is 2
5y*2 = 10y
8*2 = 16
The missing values are 10y and 16
Answer:
12.99
Step-by-step explanation:
I divided 3 by 0.231, 5 by 0.385, and 10 by 0.77 and got 12.99 for each.
