a^2=b^2+c^2
×=11; a^2=(6×11+7)^2+(3×11)^2
a^2=6418
so the length is estimately 80.11
4t ^ 2 - 16 ÷8 ÷ t - 2 ÷6
=(4t ^ 2)-(16 ÷8 ÷ t)-(2 ÷6)
=(4t ^ 2)-(2/t)-1/3
=4t ^ 2-2/t-1/3
Answer:
1
Step-by-step explanation:
1+1/1=2
Answer:
a= -3, b= -5, c= -1
Step-by-step explanation:
Quadratic Equation: 
Hope this helps!
Let x be number of T-Shirts made.
Therefore,
Revenues from the sell = 12*x = 12x
The cost making them = 20+(8*x) = 20+8x
Profits = 12x-(20+8x) = 12x -20-8x = 4x - 20
Now, this profit should be atleast $100. Then,
100<4x-20 => 100+20<4x => 120<4x => 120/4<x => x>30
Therefore, more than 30 T-shirts should be made in order to make atlease $100 profit.
