Answer:
Multiply the first two binomials: (x+2) & (x+4) using the FOIL method (First, Outer, Inner & Last).
(x+2)(x+4) = x^² + 4x + 2x + 8 = x^² + 6x + 8
Then we multiply the trinomial that we got from the first stage and multiply that by the remaining binomial:
(x^² + 6x + 8) (x + 4)
= x^³ + 4x^² + 6x^² + 24x + 8x + 32
Collect the like terms together to give you:
x^³ + 10x^² + 32x + 32
Answer:
y=0.25x
We can think of k as an unknown number.
8×_=2.00
12×_=3.00
20×_=5.00
If we divide 2 with 8 we are left with 0.25.
It's the same for the other numbers so we know the constant is 0.25.
When we use the formula y=0.25x with the numbers above, it is correct.
8×0.25=2.00
12×0.25=3.00
20×0.25=5.00
Answer:
24
Step-by-step explanation:
24 x 24 = 576
Answer:
C) A histogram because the class organizes the data into different ranges or intervals.
Step-by-step explanation:
A histogram is a graphical representation of numerical data. It is an approximate approach that groups a set of data into ranges on the x axis and having their match frequencies on the y axis.
A histogram makes it possible to represent a large amount of data and frequency in just one graph because of the interval/range option.
Because Mariner Middle school has a large number of students (550) and their height organized into equal intervals, the histogram is the best option.
