Lucas and Tony were trying to solve the equation:
x^2=16x+25x
2
=16x+25x, squared, equals, 16, x, plus, 25
Lucas said, "The x^2x
2
x, squared term is isolated, so I"ll take the square root of both sides and solve."
Tony said, "I'll solve using the quadratic formula with a=1a=1a, equals, 1, b=16b=16b, equals, 16, and c=25c=25c, equals, 25."
Answer:
neither
Step-by-step explanation:
Lucas and Tony were trying to solve the equation:
x^2=16x+25x
2
=16x+25x, squared, equals, 16, x, plus, 25
Lucas said, “The x^2x
2
x, squared term is isolated, so I"ll take the square root of both sides and solve.”
Tony said, “I'll solve using the quadratic formula with a=1a=1a, equals, 1, b=16b=16b, equals, 16, and c=25c=25c, equals, 25.”
Whose solution strategy would work?
Neither Lucas's approach for the solution is correct nor Tony's approach.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Lucas approch,
x² = 16x + 25
√x² = √16x + 25
x = √16x + 25
No further solution by Lucas,
Now,
Toy's approach,
for equation,
x² = 16x + 25
Using quadratic formula he figured it out a = 1, b = 16 ad c = 25, which is wrong from the equation a = 1, b = -16, and c = -25.
Thus, Neither Lucas's approach for the solution is correct nor Tony's approach.

Darell parks his car in a parking garage. The garage charges a certain amount for the first hour and an hourly rate for each additional hour. The total charge for 3 hours is $10.65. The total charge for 6 hours is $15.30.
Complete the equation that describes the relationship between the total charge, C, and the length of time in hours, h.
c = __ h + __
Answer:
charges for the first hour = $7.55
charges for each additional hour = $1.55
c = 1.55h + 7.55
Step-by-step explanation:
Let
x = charges for the first hour
y = charges for each additional hour
x + 2y = 10.65 (1)
x + 5y = 15.30 (2)
Subtract (1) from (2)
5y - 2y = 15.30 - 10.65
3y = 4.65
y = 4.65/3
= 1.55
y = $1.55
Substitute y = 1.55 into
x + 2y = 10.65
x + 2(1.55) = 10.65
x + 3.10 = 10.65
x = 10.65 - 3.10
= 7.55
x = $7.55
c = 1.55h + 7.55
