Answer:
1: she used the wrong formula
2: 36cubic feet
3: the strategy: knowing that to find the volume of a rectagle is l*w*h and subtituting in the correct numbers
Step-by-step explanation:
1: to find the volume of a rectangle is height*width*length
2: you multiply 6*5*1.2 and you should get 36 and sice you are finding volume it is cubic and the measurment

Answer:
two real, unequal roots
Step-by-step explanation:
This is a quadratic equation. The quadratic formula can be used to determine how many and what kind of roots may exist:
Find the discriminant, which is defined as b^2 - 4ac, if ax^2 + bx + c = 0. In this case, a = 1, b = -2 and c = -8, so that the discriminant value is
(-2)^2 - 4(1)(-8), or 4 + 32 = 36.
Because the discriminant is real and positive, we know for certain that we have two real, unequal roots
38 - 171 divided by 19 times 2
