First question
Volume = height * radius*radius*3.14
5*3*3*3.14 = 141.3 in3

Second qustion

What is the set of all solutions to the equation \sqrt{x + 2}= {-x} x+2 =−xsquare root of, x, plus, 2, end square root, equals

NARA [144]

Answer:

$x = 2$ or $x = -1$

Step-by-step explanation:

Given

$\sqrt{x + 2}= {-x}$

Required

Find the possible values fo x

$\sqrt{x + 2}= {-x}$

Square both sides

$( \sqrt{x + 2})^2= ({-x})^2$

$x + 2 = x^2$

Equate to 0

$x^2 - x - 2 = 0$

Expand

$x^2 + x -2x - 2 = 0$

Factorize:

$x(x + 1) - 2(x + 1) = 0$

$(x -2)(x +1) = 0$

Split:

$x - 2 = 0$ or $x + 1 = 0$

$x = 2 + 0$ or $x = 0-1$

$x = 2$ or $x = -1$

Destiny just received two separate gifts from her great-great-grandmother. The first gift is a box of 181818 chocolate candy bar

guajiro [1.7K]

Greatest common factor of 18 and 12 is 6

18/6 = 3
12/6 = 2

so she can make 6 bags...each containing 3 chocolate bars and 2 bags of cookies
