Answer:
yes rachel is correct
Step-by-step explanation:
because 10%+20%=30%
4x+40
4 (x+10)
distribute
4x + 4*10
The image shows the following:
adjacent² + opposite² = hypotenuse²
6² + opposite² = 10²
36 + opposite² = 100
opposite² = 64
opposite = 8
sin = = = <em>reduced</em>
cos = = = <em>reduced</em>
tan = = = <em>reduced</em>
csc = = = <em>reduced</em>
sec = = = <em>reduced</em>
cot = = = <em>reduced</em>
thx for free points
x = 14
2x+4 - 12 = 20
2x - 8 = 20
2x = 28
