Answer:
15r² - 14x - 8
Step-by-step explanation:
- 5x * 3x = 15x²
- 5x * -4 = -20x
- 2 * 3x = 6x
- 2 * -4 = -8
Now add your products,
15x² + -20x + 6x + -8 = 15x² - 14x - 8
Answer:
3/10 + 2/5 = 7/10
Step-by-step explanation:
3/10 shall stay 3/10.
2/5 will be changed into 4/10, because 1/5 = 2/10
Add: 4/10 + 3/10 = 7/10
Hope this helps :)
First you need to find a common denominator. To do that, you have to look at the denominators of the two fractions. They are 6 and 4. The closest number that they can both go into is 12. 6x2=12, 4x3=12. Then, what you multiplied the denominator by to get the number 12, you have to multiply the numerator, too.
So, it would be 8/12 + 6/12. That is 14/12, or 1 1/6. Then you add that to the whole numbers, 6 and 4, which is 10. 10 + 1 1/6= 11 1/6.
The answer is 11 1/6
So sorry that took so long
The difference between the cups of sugar is 1/6, hence you have enough sugar.
<h3>Difference and sum of fractions</h3>
Fractions are written as a ratio of two integers, For instance, a/b is a fraction where a and b are integers.
According to the question, a recipe calls for 2 1/2 cups of sugar. If have 2 2/3 cups of sugar;
Difference of cups of sugar = 2 2/3 - 2 1/2
Convert to improper fraction
Difference = 8/3 - 5/2
Difference = 16-15/6
Difference = 1/6
Since the difference between the cups of sugar is 1/6, hence you have enough sugar.

The correct statement is Triangle B is a reflection of triangle A across the x-axis. Triangle C isn't a reflection of triangle A.
Given that in a coordinate plane, triangle A is reflected across the x-axis to form triangle B. Triangle A is rotated to form triangle C.
From the given figure , it says that Triangle B is a reflection of triangle An across the x-pivot. Triangle C isn't a reflection of triangle A" in light of the fact that Triangle A is in the main quadrant and its appearance with x-axis makes the triangle-B in the fourth quadrant and the triangle C which is in second quadrant can not be a reflection and annot be a rotation of triangle-A. Triangle C is drawn by taking firstly the reflection of triangle A and then rotate on the same place and increased x+3 units in above direction.
Hence, the statement correctly describes the diagram is "Triangle B is a reflection of triangle A across the x-axis. Triangle C isn't a reflection of triangle A".
