The multiplicative identity shows us that any time you multiply something by the number 1, the result would be what you started with.
Ex: 1(m) or 1 x m.
The reason for thusbis that when you are multiplying you are representing groups of something, so 1 group of anything or m, would just be that anything or m in this case!
Answer:
its wrong
Step-by-step explanation:
So you know that the area is (b*h)/2
A = (6,6*4,9)/2 = 32,34/2 = 16,17 cm^2
Step-by-step explanation:
you can write it as
the sum of of thirty six(36) and four(4) is divided by Ten(10)
Take out - 1
k(x) = -1(x^2 - 2x - 15) Now factor what's inside the brackets. The numbers you pick must add to - 2 and multiply to -15.
When you multiply to -15 you should note that one of the numbers is plus and the other is minus.
(x - )(x + ) is the way it looks.
They differ by 2 and the "largest" one is minus. That means your answer is -5 and +3
k(x) = - (x - 5)(x + 3)
Now for the zeros.
x - 5 can be a zero
x - 5 = 0
x = 5
x + 3 = 0
x = - 3
