Answer:
what's the ratio?
Step-by-step explanation:
If the ratio of the posters' perimeter is 4:5 and the larger one is 85 inches, then we may want to know how much is one "part" of the ratio - so we divide 85 by 5:
85 / 5 = 17
So the larger poster is 5 * 17 = 85, and the smaller one is 4 * 17 = 68.
5^2 +12^2= diagonal^2
25+144=d^2
169= d^2
D= 13
In quadrilateral PQRS, ∠P and ∠S are opposite angles.
F(6) = 2(6) + 1
= 12 +1
= 13
f(3) = 2(3) + 1
= 6 + 1
= 7
f(-5) = 2(-5) + 1
= -10 + 1
= -9
