The question is asking to choose among the following choices that sates the are of the circle as shown in the diagram if the shaded sector is approximately 7.5, and base on my calculation, I would say that the answer would be 45cm^2. I hope you are satisfied with my answer and feel free to ask for more
Answer:
26 cm
Step-by-step explanation:
The sides of the quadrilateral are tangents to the circle.
Tangents drawn from an external point to the circle are congruent, hence
Beginning from the left side of the quadrilateral and counting anti- clockwise
3 + 4 + 4 + 4 + 4 + 2 + 2 + 3 = 26 cm
To simplify (-2+b^2)-(7+b^2), first distribute the -1 to both terms in the second parenthesis.
-2+b^2-7-b^2
Combine like terms.
-9 (1-1=0, so the b^2 is canceled out.)
(-2+b^2)-(7+b^2)=-9
Answer:
-25
Step-by-step explanation:
2a² - 5a + 4, for f(-3)
2(-3)² -5(-3)+4
2*(-27)+15+4
-54+19
= -25
The 2 is in the tenths place so it's 2/10 or two tenths. : )
