3 and 1 are divisible by 3. 3, 1, and 9 are divisible by 9
So,
You have to undistribute a common factor in all of the terms.
2a + 2b
There is a 2 in each term.
Undistribute.
2(a + b)
Question is unclear to me ,, can you rewrite it in a nicer way so i can answer?
Answer:
Width=28 1/3 Length=51 2/3
Step-by-step explanation:
1. Create an equation
x+(2x-5)=80
2. Solve
x+(2x-5)=80
3x-5=80
3x-5+5=80+5
3x/3=85/3
x=28 1/3
So, if x=28 1/3
85/3x2=170/3
56 2/3-5
So, Length=51 2/3
First subtract 2 revolutions from the - 840 :- (- (840-720) = -120
This gives sin -120 which is in the 3rd quadrant of the unit circle
sin -120 = - sin 60 = - sqrt3/2
