Answer:

Step-by-step explanation:
a²+b²=c² so: 33²+15²=x²
1089+225=x²
1314=x²
take the square root of both sides
36.249=x or

=x
Answer:
4x-8
Step-by-step explanation:
y=-x2+6x-8
y=4x-8
Well,
we know that we need to accumulate points from x and y to reach 20 points.
since x provide 3 and y provide 4 points, the formula would be :
3x + 4y = 20
or it can be written as :
y = (3x/4)+5
hope this helps
2 + 1 = 3
3 - 3 = 0
Hope this helped :)
