Answer:
(C
) b(x)=4(x+2)(x−2)
Step-by-step explanation:
We are given
The number of blue tiles in her design is modeled by the function b(x)=
if the no of blue tiles used is zero then
b(x) = = 0
= 4
x = +2 and -2
this is the condition for blue tiles
Modelling
b(x) = 4(x+2)(x-2)
This means when the blue tiles used are zero, then we use 2 red tile on each of the two square of 4 square. so the length will be 4 tiles long and its a square so 4x4 = 16 red tiles.
If the old perimeter was dilated with a scale factor of 3, then it should be multiplied by 3 to find the new perimeter.
30 times 3 = 90 inches, which is the answer
Answer:
About 68% (is that an answer choice?)
Step-by-step explanation:
In a normal distribution (a bell curve), about 68 percent of the data is in the range between one standard deviation below the mean to one standard deviation above. If your mean is 27, and the standard deviation is 3, then one deviation below to one above would be 27 - 3 to 27 + 3, or 24 - 30.
The next two numbers are 20, -4
