Answer:
396
Step-by-step explanation:
Difference of two squares is breaking down numbers into pieces and using the distributive property to solve. The pieces should be in the form (a-b)(c+d).
Write 22 as (20 + 2) and 18 as (20-2).
(20+2)(20-2) = 400 + 40 - 40 - 4 = 400 - 4 = 396
To get the reciprocal, simply flip the numerator and denominator. The reciprocal of 3/10 is 10/3.
So 2% is 2/100. That would be 0.02.
You can make 36 banners. there are 3 feet in 1 yard so if you multiply 12 and 3 you get 36
Use the unit circle to find the inverse function value in degrees.tan^-1 sqrt 3
The correct answer would be 60 degrees. Since you are asked to find an angle that the tangent is equal to sqrt 3. The only angle that is equal to that given the interval is 60 degrees. So that is the correct answer. I hope this answer helped you.
