Answer:
BE = 49
Step-by-step explanation:
In triangle BDC
65^2=56^2+BD^2
65^2-56^2=BD^2
4225-3136=BD^2
1089=BD^2
33=BD
In triangle FDE
65^2=63^2+DE^2
4225-3969=DE^2
256 = DE^2
16=DE
since ED+DB=BE
THEREFORE
16+33=BE
49=BE
Yea that can be a good equation. I had this question last year and my teacher said it was ok.
But it can be wrong, I don't really know. Cuz we don't go to the same school.
You must equal zero, so that way 2x can equal 2x
The volume of the cone is 18.85
Let's imagine the integers are a, b, and c. Since we know the sum of these numbers is 50 more than the smallest (which is a), our equation would look like this:
a + b + c = a + 50
We need a common variable, though, which we don't have right now. Since we know that these are 3 consecutive <em>even </em>integers, we know that:
b = a +2, which means that the second number is 2 more than the first number.
Using that same logic, we know that c = b +2 and since we know what b equals, we can sub that into this:
c = b + 2
c = (a + 2) + 2
c = a +4
So now instead of having this:
a + b + c = a + 50
We have this:
a + (a + 2) + (a + 4) = a + 50
3a + 6 = a + 50
Subtract a + 6 from both sides:
3a + 6 - (a + 6) = a + 50 - (a + 6)
2a = 44
Divide both sides by 2
2a/2 = 44/2
a = 22
The smallest integer is 22 which means the set would be:
22, 24, and 26
