This is the answer that I came up with 12x^2-14x-6x+7 this is because the 2x and the 6x are multiplied together and then the 2x and the -7 are as well and the same is true of the -1 and the 6x and the -1 and the -7.
She uses 11/36 yards of string for each.
In this problem, you're dividing the amount of string by the number of banners, so 11/12 ÷ 3. To do this though, it's easiest to convert the 3 into a fraction. After you do this, you're left with:
11/12 ÷ 3/1
When dividing fractions, you flip the second fraction upside down and change the operation to its opposite, which gives you:
11/12 × 1/3
Then you just multiply across. 11×1=11 and 12×3=36, so you're left with 11/36 yards of string.
Answer: in pounds an average weight of an adult would be 180lb (or 81.6466266kg but 80kg will also be the answer
Step-by-step explanation:
Some key definitions:
<u>Reflexive property:</u> angles, line segments, shapes are congruent to themselves. Its easier to think of a shape: if you have a circle, then this circle is equal to itself.
<u>Symmetric property:</u> you can interchange the equal signs of an equation. So think of a=b is the same as b=a, its just the same thing written in a different order.
<u>Transitive property:</u> If a=b, and b=c, then a=c. Basically think of it as a=b=c, all of these variables are the same as each other.
So for the first clue, you have the reflexive property.
The second clue is the symmetric property.
The third clue is the transitive property.
I like to change all the subtraction to addition of the negative.
4x^2 + 8x + (-11x) + 6 + (-5x^2) + 2
Now combine the like terms.
-x^2 -3x + 8
Your answer is A: -x^2 - 3x + 8
