Cartesian product: (Find the value of x and y in each of the following)
I know the answer, but can anyone explain it with steps?

In triangle opq right angled at p op=7cm,oq-pq=1 determine the values of sinq and cosq

Since opening night, attendance at play a has increased steadily, while attendance at play b first rose and then fell. equations modeling the daily attendance y at each play are shown below, where x is the number of days since opening night. on what day(s) was the attendance the same at both plays? what was the attendance? play a: y = 8x + 191 play b: y = -x^2 + 26x + 126

Solve the equation for x.3(6x - 1) = 12 i've tried doing the math and i can't find out what i'm doing wrong
