I think the answer is (-6,30) unless I messed up somewhere
Step-by-step explanation:
Let x represent the number.
We have 2x + 18 = 3x - 5, therefore x = 23.
The number is 23.
X would equal 60 degrees because the degree of the top left area is equal to the degree of the bottom right. So the equation would be x+20=80 so you would solve to get x=60
x+x+y.y.y = 2x+y^3 ( y cube)
So, The answer is (d)
