Your answer would be (B) 44.0, because circumference is calculated using the formula 2π(r). When you plug in the known values you would get 7pi ≈ 22. Then you would do 2*22 and get 44.0. Hope this helps! (I also put the answer in the ask for details section)
Answer:
x=−0.485981
idk how to round to the nearest tenth
Step-by-step explanation:
I turn the mixed numbers into decimals before doing anything else.
11 2/5----> 57/5----> 11.4
4 2/7----> 30/7----> 4.29
2 1/7----> 15/7----> 2.14
11.4=q-4.29+2.14
11.4=q-2.15
13.55= q
13.55 converted to a fraction is 13 11⁄20
q=13 11⁄20
Answer:
- 8x² + 36xy - 36y²
Step-by-step explanation:
Given
(- 2x + 6y)(4x - 6y)
Each term in the second factor is multiplied by each term in the first factor, that is
- 2x(4x - 6y) + 6y(4x - 6y) ← distribute each parenthesis
= - 8x² + 12xy + 24xy - 36y² ← collect like terms
= - 8x² + 36xy - 36y²
