Answer:
<em>4</em> and <em>5</em>
Step-by-step explanation:
xy = 20
x + y = 9 ⇒ x = 9 - y
y(9 - y) = 20
9y - y² = 20
y² - 9y + 20 = 0
D = ( - 9)² - 4(1)(20) = 81 - 80 = 1
= (9 + 1) ÷ 2 = 5
= (9 - 1) ÷ 2 = 4
The numbers are <em>4</em> and <em>5</em>
A) a(x^2+ b/a x)+ -c
1/2
Sine is opposite over hyp.
So the opp is 5 and the hyp is 10
5/10 equal 1/2
that's something uuuuyuuyyyy
