The length of the room is 156 sq in
X^2+10x+29=0
Quadratic Formula:
−b±√b^2−4(ac)/2a
Substitute the values :
a=1, b=−10, and c=29
into the quadratic formula and solve for
x.
10±√(−10)^2−4•(1•29)/ 2•1
Simplify.
Answer: x=5±2i
Answer:
800 miles
Step-by-step explanation:
Set up an equation, where x is the number of miles driven:
0.10x + 120 = 200
Then, solve for x:
0.10x = 80
x = 800
So, the maximum number of miles he can drive is 800 miles
