Answer:

Height of cone (h) = 14.8 in (Approx)

Step-by-step explanation:

Given:

Radius of cone (r) = 6 in

Slant height (l) = 16 in

Find:

Height of cone (h) = ?

Computation:

Height of cone (h) = √ l² - r²

Height of cone (h) = √ 16² - 6²

Height of cone (h) = √ 256 - 36

Height of cone (h) = √220

Height of cone (h) = 14.832

Height of cone (h) = 14.8 in (Approx)

Square root of 5u+2 = square root of 3u+14
alina1380 [7]
Sqrt(5u + 2) = sqrt(3u + 14)
Square both sides to clear the square root.
5u + 2 = 3u + 14
subtract 3u from both siides
2u + 2 = 14
subtract 2 from both sides
2u = 12
divide both sides by 2
u = 6
When you square a square root you MUST check the solution.
sqrt(5*6 + 2) = sqrt(3*6 + 14)
sqrt(32) = sqrt(32)

4x-y=20 and -2x-2y=10
lara31 [8.8K]

You can use Substitution to solve this problem:


4x-y=20

-y=-4x+20

y=4x-20


Now you have two equations, and you use the first one to substitute into the second one.


y=4x-20     and     -2x-2y=10


-2x-2(4x-20)=10

-2x-8x+40=10

-10x+40=10

-10x=-30

-x=-3

x=3


Now that we have figured out what x is, we can substitute x in to one of the equations to figure out y.


4x-y=20       x=3

4(3)-y=20

12-y=20

-y=8

y=-8



<em><u>So your answer would be x=3 and y=-8</u></em>
