Write an equation in which the quadratic expression 2x^(2)-2x-12equals 0. Show the expression in factored form and explain what your solutions mean for the equation. Show your work.

Answer:

Answers

Answer 1

Answer:

Begin by factoring 2 out of 2x^2 - 2x - 12 equals 0:

2(x^2 - x - 6) = 0

2(x - 3)(x + 2) = 0. 2 is never zero, but x-3 and x+2 can each be set = to 0:

This results in x = 3 and x = -2. The equation is true for these two x-values.

Describe two ways the Distributive Property can be used to write equivalent expressions.

Answers

For example, apply the distributive property to the expression 3 (2 + x) to produce the equivalent expression 6 + 3x; apply the distributive property to the expression 24x + 18y to produce the equivalent expression 6 (4x + 3y); apply properties of operations to y + y + y to produce the equivalent expression 3y.

The two ways for the Distributive Property can be used to write equivalent expressions is explained below:

Distributive Property:Here we apply the distributive property to the expression 3 (2 + x) to generate the equivalent expression 6 + 3x.Now apply the distributive property to the expression 24x + 18y to generate the equivalent expression 6 (4x + 3y)

Kathryn is cooking pancakes. The recipe calls for 3 2/9 cups of flour. She accidentally put in 5 4/5 cups. how many extra cups did she put in?

Answers

subtract
29/5 - 29/9
261/45 - 145/45
116/45

Answer

So basically you need to subtract 5 4/5 - 3 2/9

then you do all this:

= (5-3) + (4/5 - 2/9)

= 2+ 4x9/5x9 - 2x5/9x5

= 2 + 36/45 - 10/45

= 2 + 26/45

= 2 26/45

So then the answer is 2 26/45

5-4t = 6

Answers

The answer is negative one fourth.

t = 1/4

-----

First, rearrange the subtraction problem

5 - 4t = 6 is the same as -4t + 5 = 6

-----

Next, subtract 5 from both sides

-4t + 5 - 5 = 6 -5

This is known as the Subtraction property of equality.

-----

Then, since 5-5 is 0 and 6-5 is 1

-4t = 1

-----

Then, you would divide that so

-4/-4 = 1/-4

-----

So your answer would be

1/4!
