7.2(2.8r-4.5s)+9.34r -1.25s
=20.16r - 32.4 +9.34r -1.25s
=29.5r - 33.65s
So the answer is A
hope I can help u
Answer:
Step-by-step explanation:
7/8π
The circles have the same central angle measures; therefore, the ratio of the intercepted arcs is the same as the ratio of the radii.
4/7 = 1/2π over x
x = 7/8π
(2x² + 6x + 10) + (4x² + 2x + 3)
Remove the parentheses and bring like terms together ( as there's a positive outside the parentheses the terms inside keep their signs):-
= 2x^2 + 4x^2 + 6x + 2x + 10 + 3
= 6x^2 + 8x + 13 answer
Answer:
5
Step-by-step explanation:
The answer is 5 because all angles are congruent.
