1 and 7 because they have the same angles
Yes it is correct .
45 plus 90 =135
which means that 135 - 45=90
I'm not sure exactly what it means in mathematics, other than putting similar things into groups.
So I guess you could answer with organizing similar things into group like the heights, favorite colors, ages, and grades of people in your class or something.
Is that what you're looking for?
Answer:
- 2x - 7y
Step-by-step explanation:
Given
- (4x + y) + 2(x - 3y)
Distribute both parenthesis, noting that the first is distributed by - 1
= - 4x - y + 2x - 6y ← collect like terms
= (- 4x + 2x) + (- y - 6y )
= - 2x + (- 7y) = - 2x - 7y
64÷2=32......................
