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

Step-by-step explanation:

Verify the solutions of each quadratic function

case 1) we have

Adds 25 both sides

take square root both sides

case 2) we have

Subtract 10 both sides

take square root both sides

case 3) we have

Adds 9 both sides

take square root both sides

case 4) we have

Subtract 49 both sides

take square root both sides

Compare the solutions

The largest positive solution is x=13

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

the 1st digit is in the 100s n its 1

step-by-step explanation:

3,589÷18 = 199.389

so the first digit of the quotient is in the 100s n its 1
