A.) 13. all you have to do is plug it into google
You basically simplify for this one,18 / ? = 9
18/2=9
So in this case, 8*2 is 16! Hope this helps!
sin α = opposite leg/ hypotenuse
For ΔABC,
sin A = |BC|/|AB|
sin A = 12/37
Distribution method
(2x+6)(2x-6)
=4x^2-12x+12x-36
=4x^2-36
No. You have to calculate the unit rate by dividing 30 and 6 which is 5. Then 40 divided by 18 which is 2.22 repeating. since they don't equal the same thing, it is false.
