The first and last choices are true.
First Choice:
7 of a total of 16 cells should be shaded.
Last Choice:
Double the numerator and denominator of 6:8. 12 is greater than 7 (12:16 and 7:16)
Hope it helped and I hope those are the correct answers.
=4m - 17+ 3m - 11
combine like terms
=(4m + 3m) + (-17 - 11)
=7m - 28
This can be factored/simplified by dividing everything by 7
=7(m - 4)
Hope this helps! :)

Answer:
sin(x) = 5/13
cos(y) = 5/12
Therefore, sin(x) = cos(y)
Step-by-step explanation:
Trig ratios:
where 
is the angle, O is the measure of the side opposite the angle, A is the measure of the side adjacent to the angle and H is the hypotenuse, of a right triangle
We have been given the measures of the two legs, so we can find the measure of the hypotenuse by using Pythagoras' Theorem 
(where a and b are the legs and c is the hypotenuse of a right triangle)
Now we can use the trig ratios:
Therefore, sin(x) = cos(y)
Let n be one side of the square wood block. Then:
n²=872
n=√872=approx. 30" per side
