Answer:
<h2>18</h2>
Step-by-step explanation:
The formula of a distance between two points:
We have the points (5, -7) and (5, 11). Substitute:
Answer:
3
Step-by-step explanation:
As we move from A(2, 1) to B(5, 1), x increases by 3 but y stays the same.
Thus, the distance from A to B is simply 3. This is the desired length.
Here is a simplified and how to solve i have another way to solve it to so I will send u it
Answer:
it will be a positive number that is even
Step-by-step explanation:
this is because two negative numbers multiplied make a positive and two odd number multiplied make an even.
please leave a thanks if im correct
So say for example we have
x5−3x3−2x2+6
We group the terms together by 2's
(x5−3x3)−(2x2−6)
Notice how that highlighted '-' is there...it WAS '+' but since we have a '-' in front of the parenthesis...when that distributes..it turns that '+' '-' again So now...we factor out of each parenthesis what we can... x^5 - 3x^3 ...well looks like at least x^3 can come out of there 2x^2 - 6 ...well we can factor a 2 out of there.. so now we have
x3(x2−3)−2(x2−3)
Now notice how we have 2 parenthesis that have the same thing inside them...and we also have 2 coefficients of those parenthesis...so we put those together respectively
(coefficients in here)(those things in the parentheis since they are the same)
(x3−2)(x2−3)
Everything make sense?
Well say we have
3x2+10x−8
We can actually break up that 10x ...and make it -2x + 12x right? since -2 + 12 =10 so we would then have
3x2−2x+12x−8
NOW we can group these up by 2's
(3x2−2x)+(12x−8)
Lets factor out an 'x' of the first set of parenthesis...and also lets factor out a 4 of the last set...
x(3x−2)+4(3x−2)
Look the same thing as before...same thing in both parenthesis.and 2 coefficients outside...so again
(x+4)(3x−2)
