8x+28-2
The answer is 8x+26
3-5 is equal to -3 not positive 3 cause it's mines, less than 0.
Hope this help!
If it's wrong sorry cause I understand the question like this
Answer:
-7x⁸ + 5x⁷ - 11x + 2
Explanation:
Before we begin, remember the following:
(-ve) * (-ve) = +ve
(-ve) * (+ve) = -ve
(+ve) * (+ve) = +ve
(+ve) * (-ve) = -ve
Now, for the given we have:
(5x⁷ - 8x + 2) - (7x⁸ + 3x)
First, we will get rid of the brackets based on the above rules. This will give us:
5x⁷ - 8x + 2 - 7x⁸ - 3x
Next, we will combine like terms as follows:
5x⁷ + (-8-3) x - 7x⁸ + 2
This will give us the final expression:
-7x⁸ + 5x⁷ - 11x + 2
Hope this helps :)
There are 50 sections.
Step-by-step explanation:
Given,
Length of section = 10 meters
Total length of guardrail = 0.5 km
We will convert this length in meters.
1 km = 1000 meters
0.5 km = 0.5*1000 = 500 meters
Now,
No. of sections =
No. of sections =
No. of sections = 50
There are 50 sections.
