100pointswhich quadratic function has the largest positive solution x^2-25=0
x^2+10=154
x^2-9=160
x^2+49=50

The equation that gives the largest possible solution of ‘x’ is

Option C

Step-by-step explanation:

Solve for ‘x’ for all given options to find largest possible solution.

Case A:

Taking square root for ‘25’, we get  x = 5

Case B:

Taking square root for ‘144’, we get ‘x’ as x = 12

Case C:

Taking square root for ‘169’, we get ‘x’ as  x = 13

Case D:

Taking square root for ‘1’, we get ‘x’ as  x = 1

Hence, the equation that gives the largest possible solution of ‘x’ is Option C:

whatever you can spend with $11.53 or under.

step-by-step explanation:

20 - 8.47 = 11.53. take away the money he used for lunch from the starting amount of 20.

t = 3

step-by-step explanation:

put t = 3 in this expression :

(3²-1)(3²-2)(3² - 3)(3² - 4) = 8×7×6×5 = 56×30 = 1680
