Luis spends $14.76 all together
Yes because 9+4 = 13 and if you plug in the y and x it turns out true
<h3>
Answer: Approximately 23.0 cm</h3>
=====================================================
Work Shown:
a = 20.3
b = unknown
c = 30.7
Apply the pythagorean theorem to find b
a^2 + b^2 = c^2
(20.3)^2 + b^2 = (30.7)^2
412.09 + b^2 = 942.49
b^2 = 942.49-412.09
b^2 = 530.4
b = sqrt(530.4)
b = 23.0304146727757 value is approximate
b = 23.0
I rounded to one decimal place because the other values (20.3 and 30.7) were to one decimal place.
Show me the picture of the octagon. But remember that if the diameter is shown than always do half of the diameter to get the radius. Hope this helps
F(x) = (-3)2 - 5(-3) + q
= -6 + 15 + q
= 9 + q
