It should be A. Just factor 45
Answer:
π/2 or 1.57 square units
Step-by-step explanation:
The area of a sector with central angle θ is given by the formula ...
A = (1/2)r²θ
Filling in the given value, we find the area to be ...
A = (1/2)(3²)(π/9) = π/2 . . . . square units
Using 3.14 for π, this is ...
A = 3.14/2 = 1.57 . . . . square units
You just do 1/1 then multiply that by 7 which would be 7/7. Then do 7/7 - 3/7 which would be 4/7 (which can not be simplified)
Answer:
C) -4
Step-by-step explanation:
this is correct as far as i know.
To simplify this expression, we can combine like terms.
= 11x - 7 - 3x + 4
= (11x - 3x) + (-7 + 4)
= 8x - 3
Best of Luck!
