Put 16 where n is, then do the arithmetic.

... a(16) = -6 + 3(16 -1)

... a(16) = -6 + 45

... a(16) = 39

The answer is 39 because you have to plug in 16 for (n-1). Then you do 16-1=15. Then you do 3(15) which is 45. Then you do -6+45=39.

The radius of a cylinder is 3x – 2 cm. The height of the cylinder is x +3 cm. What is the

VashaNatasha [74]

Surface Area of the cylinder is 6x² + 83x - 58 cm²

Step-by-step explanation:

Step 1: Given surface area of the cylinder, A = 23r + 2rh. Here, r = (3x - 2) and h = (x + 3)

⇒ A = 23(3x - 2) + 2(3x - 2)(x + 3)

⇒ A = 69x - 46 + (6x² + 18x - 4x - 12)

⇒ A = 6x² + 83x - 58 cm²

Solve the radical equation x – 7 = square root of -4x+28. Which statement is true about the solutions to the radical equation? T

Julli [10]

Answer:

x = 3 and 7

There are two true solutions.

Step-by-step explanation:

To solve $x-7 = \sqrt{-4x+28}$ , use inverse operations by squaring both sides of the equal sign.

$(x-7)^2 = (\sqrt{-4x+28})^2\\x^2-14x+49 = -4x+28\\x^2-14x+4x+49-28 = 0\\x^2-10x+21=0$

The quadratic expression can be factored into binomials and set equal to 0 by the zero product property to find x.

(x - 3) ( x - 7) = 0

x-3 = 0 so x=3

x-7 = 0 so x=7

Now check each solution into the original equation to be sure it solve the solution and is not extraneous.

$7-7 = \sqrt{-4(7)+28}\\ 0=0$

and

$3-7 = \sqrt{-4(3)+28}\\[tex]-4 = \sqrt{16}\\-4 =-4$ [/tex]
