Find the solution set for this equation.

Answer:

t = 0, t = - 2

Step-by-step explanation:

Given

- t² - 2t = 0 ← factor out t from each term

t(- t - 2) = 0 ← in standard form

Equate each factor to zero and solve for t

t = 0

- t - 2 = 0 ( add 2 to both sides )

- t = 2 ( multiply both sides by - 1 )

t = - 2, thus

solutions are t= 0, t = - 2

Vickie made a recipe for 144 fluid ounces of scented candle wax. How many 1-cup candle molds can she fill with the recipe

Gre4nikov [31]

there are 0.125 cups inside 1 fluid ounces

144 / 0.125 = 1152 (divide because you are trying to figure out how many of the volumes of the mold can fit inside the 144 fluid ounces

You can fill 1152 molds with 144 fluid ounces

please help me figure out the length of side AC!!!! i put the points at 16! i need this by the 21st :(

Ilia_Sergeevich [38]

Answer:

AC = $\sqrt{89}$ units²

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse AC is equal to the sum of the squares on the other 2 sides, that is

AC² = AB² + BC² = 5² + 8² = 25 + 64 = 89 ( take square root of both sides )

AC = $\sqrt{89}$ ≈ 9.43 ( to 2 dec. places )
