Hey there!
When finding the difference of expressions like these, there's a few things you should keep in mind.
1. When finding the difference of two polynomials, multiply the polynomial that implied to be "negative" by –1 to expand the problem and make it easier to solve.
2. You combine terms based on their unknown terms, like x, y, x², ab, etc. You cannot combine the terms x and x², but you can combine the terms 6b and 8b by adding them.
3. You can rearrange your terms however you see fit. If a polynomial is implied as "positive", you can multiply that entire polynomial by +1 to get rid of the parentheses.
With all that in mind, you can go ahead and solve for your difference, like so:






will be your difference.
Hope this helped you out! :-)
C. -5y -4 = -(x+3)^2 -1/2
Hope I am right.
Answer:0.60
Step-by-step explanation:
Multiply the denominator (5) and the numerator (3) by 20. Both sides multiplied equals 60 as the numerator and 100 as the denominator. After the conversions to a decimal, your answer should be 0.60 since 60/100=0.60.
Answer:
120°
Step-by-step explanation:
Sum of angles = (n-2)180°, where n is the number of sides.
This is a hexagon, so n=6.
Sum of angles = (6-2)180° = 720°
Each interior angle = 720°/6 = 120°
Answer:
The actual distance between the two places to the nearest tenth of a kilometer is 63.3 km
Step-by-step explanation:
Here, we want to get the actual distance between two places on a map, given the scale used to draw the map and the distance of both places on the map, in terms of the scale.
The scale used here is 1cm to 11.5km
Since 1cm = 11.5km
then 5.5cm = x km
Thus ; x = 5.5 * 11.5
x = 63.25 km
Our answer in wanted to the nearest tenth of a kilometer so the answer is 63.3 km
