Answer:
-95
Step-by-step explanation:
4+9(3+11)-15²
So, the order of operations is PEMDAS. The first thing is "P" for Parenthesis, so you would do whatever is in the parenthesis first.
3+11= 14
Now, the expression is 4 + 9 (14) - 15²
The next letter is "E" for Exponents. so the 15² has an exponent, so you do 15 x 15.
4+9(14)-225
Next is "M" for Multiplication. A number next to a parenthesis can mean multiplication as well. So, you do 9 × 14 = 126
Now, it's 4 + 126 - 225
Since there is only addition and subtraction left, you go left to right.
4 + 126 = 130
130 - 225 = -95
Hope this helps !!

Answer:
Step-by-step explanation:
The graph shows A RELATION ONLY. Why? because for '25 minutes,' there is more than one y value. So what is shown is only a relation.
Without a diagram, one must make certain assumptions about this problem. If and only if these three angles are the interior angles of a triangle, then their sum must be 180 degrees, so that 18x+12 + 6y + 3x+4y = 180. Unfortunately, this is a single equation in 2 unknowns. Thus, we cannot solve for an explicit value for either x or y.
If there was a diagram, please share it; otherwise, describe the triangle in words as best you can.
Answer:
y=5x+6
