30/5= 6
6 - 2 = 4
Your number is four
3(3b+2)=-30 perform indicated multiplication on left side...
9b+6=-30 subtract 6 from both sides
9b=-36 divide both sides by 9
b=-4
Answer:
<h2>41. x = √2</h2><h2>42. x = √5</h2><h2>43. x = 4</h2><h2>44. x = 4√3</h2>
Step-by-step explanation:
The Pythagorean Theorem:





horizontal line: x=9
vertical line: y=3
You can plug it into the application demos to see it visually just put y=3 on one line and x=9 on the other
Step-by-step explanation:
tanB + cotB = (sinB)/(cosB) + (cosB)/(sinB)
= (sin2B + cos2B)/[(cosB)(sinB)]
= 1/[(cosB)(sinB)]
= (1/cosB)(1/sinB)
= (secB)(cscB)
