Each angle of the triangle added together must be equal to 180, so 53+45=98. 180-98=82. So the top angle is 82, the value of x has to be equal to 180-82 which equals 98
So to find the value of -3 do the following process:
Insert the -3 in the x’s in the equation on the top of the table
y= 5x -3x to the second power + 3
y= 5 (-3) -3(-3) to the second power + 3
Then continue to simplify the equation
y= -15 + 9 to the second power + 3
y= -15 + 84
y = 69
Y= 69 for the chart for -3
For b, c, and d insert the number in the x values and simplify like the previous equation.

Answer:
Limit is 18
Step-by-step explanation:
Using direct substitution
5x+ 2x+ 4 = 5(2) + 2(2)+ 4 = 10+ 4+ 4= 18
I wish I can help but I’m bad at this sorry!
