Let the smaller number be x
x+x+7=63
2x+7=63
2x=56
x=28
28+7=35
The two numbers are 28 and 35
32^2 +24^2 = 1600
Square root of 1600 = 40
b = 40.
More info needed for a and c.
This doesn't give me enough information to answer the question lol
Since the function and choices are already given, the simplest method would be to try out the given values of x and see if the value of y obtained and given int he choices would coincide. Using this trial and error method, it has been shown that the correct answer among the choices is choice C, with the solution shown below:
y = -0.296x^2 + 2.7x
Using (4.6, 6.2):
y = -0.296(4.6)^2 + 2.7(4.6)
y = 6.2
.25(3.6-1.25)+3.45
.25(2.35)+3.45
.5875+3.45
4.0375
