2x^2 -6x -2+x^2+4x
All you have to do is add like terms
2x^2+x^2
= 3x^2
-6x+4x
= -2x
Then add them together to get one equation
3x^2 -2x -2
I recommend you study how to add variables as these are very basic sums. Just practice :)
Answer:
6w⁴ + 8w²
Explanation:
Before we begin, remember the following:
xᵃ * xᵇ = x⁺ᵇ
+ve * -ve = -ve
-ve * -ve = +ve
+ve * +ve = +ve
To solve this problem, we will follow the following steps:
1- get rid of the brackets using the distributive property
2- combine like terms
This can be shown as follows:
w²(-4w² - 2) + (-5w²)(-2w² - 2)
w²(-4w²) + w²(-2) + (-5w²)(-2w²) + (-5w²)(-2)
-4w⁴ - 2w² + 10w⁴ + 10w²
w⁴(-4+10) + w²(-2+10)
6w⁴ + 8w²
Hope this helps :)
Answer:
Step-by-step explanation:
Multiply across.
Then Simplify.
1.) top row: 100 200 300 400 500 600. Bottom row: 5 10 15 20 25 30
2. Each ratio is just the top row divided by the bottom row. So the second thing in the ratio would be 200/10, the third one 300/15, etc. Each ratio is equal to 20.
3.) if x is gallons of gas used, y is distance driven. the equation that describes this relationship is y=20x.
