which of the following formulas would find the surface area of a right cylinder where h is the height, r is the radius, and BA i
Solnce55 [7]
The answer is B. The first part of the formula finds the base area (both top and bottom) and the second part finds the lateral area of the cylinder. It could also be A but I don’t know if the BA includes both top and bottom.

The equations were multiplied by constants and added together to determine that the value of x in the system of equations is –20
Misha Larkins [42]

Answer:

Step-by-step explanation:

Given:

1. 1/5x - 1/3y = -1

2. -3/4x +1/3y = 12

Multiplying equation 1 by 15 and equation 2 by 12

3. 3x - 5y = -15

4. -9x + 4y = 144

and then Solving both equations simultaneously, since x = -20 as stated in the question and by confirmation,

Using equation 3 or 4 to solve for y,

3(-20) - 5y = -15

-5y = 60 - 15

y = 45/-5

= -9

y = -9

Solve and check the answers in the original equation
Scrat [10]
 12 + 5k + 15                     -24
------------------- =  -----------------------
      k + 3                      k - 4
 5k + 27              -24
------------ =  ---------------
  k + 3                k - 4

 (k - 4)(5k + 27) = -24 (k + 3)
5k^2 - 20k + 27k -108 = - 24k - 72
5k^2 + 31k - 36 = 0
(5k + 36)(k - 1) = 0

5k + 36 = 0; k = -36/5 = -7.2
k - 1 = 0; k = 1

solutions
k = 1 and k = -7.2
