$2.189 there uu go.......
Answer: 3x^2 + 7x -15
I dunno if u want me to factor it tho
To find the value of a variance add and subtract the variance from the original number.
The original number is 32 hot dogs.
The variance is 5 hot dogs.
32-5 = 27
32 + 5 = 37
This means he needs to eat between 27 and 37 hot dogs.
he inequality with variance is written as: 27 < h < 37
Because the cos theta < 0 then theta must be an obtuse angle
so a^2 + b^2 < a^2
C
