h = 10.99 in

Step-by-step explanation:

Volume of a cone formula: V=πr^2*(h/3)

r is the radius of the base of the cone. The diameter of the base of your cone is 12 in. The radius is always diameter divided by 2, so the radius here is 6 in.

V is the volume. The volume of your cone is given as 414.48 in^3.

h is the height of the cone. That's the variable we need to solve for. So plug everything in:

414.48 = π (6)^2 * h/3

414.48 = π36 * h/3

414.48/ (π36) = h/3

(414.48/ (π36))*3 = h

10.99 in = h

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
