Answer:
3 : 15pm
Step-by-step explanation:
2 : 25 pm + 50 minutes
2 : 25 pm + (35 minutes + 15 minutes)
(2 : 25 pm + 35 minutes) + 15 minutes
3 : OO pm + 15 minutes = 3 : 15 pm
For a rectangular prism, the volume is,
the area of one of the faces * the length of the other unit
so say the base is 9 * 9, then, that base times the height of 16
now, for the triangular prism, the volume is,
the area of one of the triangular faces * the length of the other unit,
so... say, find the area of one of the triangular faces
recall 1/2 b*h
and then multiply that times the other length of 20
A quadratic with roots at 8 and 5 is f(x) = x^2 +12x + 20
In order to find an equation given roots you can create statements that equal 0 in order to create parenthesis. For instance we know x = 8 at one point. So, we can solve that to equal 0.
x = -2 ----> add 2 to both sides
x + 2 = 0
We can do the same for the other zero.
x = -10 ----> add 10 to both sides
x + 10 = 0
Now that we have both of these, we can multiply these two things together. This will give us the function we need.
f(x) = (x + 2)(x + 10)
f(x) = x^2 + 10x + 2x + 20
f(x) = x^2 + 12x + 20
21 divided by 2 is 10.5 and if you add 4 to it, it gives you 14.5. there you go
