F + V = E + 2

25 + 17 = E + 2

42 = E + 2

42 - 2 = E

40 = E

E = 40

Edges: 40

F + V = E + 2
F = 25
V = 17

25 + 17 = E + 2
42 = E + 2
42 - 2 = E
40 = E <== there are 40 edges

Solve for x. Write the smaller solution first, and the larger solution second. (x -4)(-5x +1)=0
Vesnalui [34]

The product of the two is 0, so one of them have to equal 0 as any number multiplied by 0 is 0.

First solution: x - 4 = 0

If x - 4 = 0, then x = 4. So the first solution for <em>x </em>is 4.

Second Solution: -5x + 1 = 0

Solving...

-5x + 1 = 0

-5x = -1

x = -1/-5

x = 1/5 or 0.2


So x = 0.2 and 4

Write the number 5267 correct to<br> the nearest hundred.
galben [10]

Answer:

5300.

If you're rounding to the nearest hundred you look at the tens place. If its 5 or over you go up. So in this case we'll raise the 2 to a 5 because 6 is above 5.
