-6x² + (-x²) = -6x² - x² = -7x²
-7x² + 15x + 4 is your answer
hope this helps
Answer:
Step-by-step explanation:
here ,
6x +238 = 3x+178 ( vertically opposite angles are equal)
so 6x - 3x = 178 -238
3x =-60
x =-60/3
x=-20

Basically estimating is rounding, im going to futher explain this with an example.
For example:
If I wanted to round a number by it's nearest tenth such as 678
(*example)
there are 70 tenths
now when you are estimating when you are rounding to the nearest number if the number has a higher value then 5 you increase the number if it is lower than 5 you STAY the same.
now
678,
since the number next to it is 8, 7 increases and everything else turns into zero. so 678 rounded to the nearest 10th
is 680!
Hope this example helped!

To solve for m, you have to get it by itself on one side of the equal sign.
To do that you have to eliminate c and r and put them at the other side.
r is being divided by m, so you have to do the opposite to get it on the other side, which is multiply. Multiplying r to both sides will remove the division, and give you <span>Er=cm</span><span>. So... B is the answer :)</span>
