Which number line represents all of the values of x for the equation x2 = 64?

We are asked to find all the values of x on the number line that satisfies the given quadratic equation:

We know that this is a quadratic equation so the number of values that we get on the number line is maximum 2.

on taking the square root on both the side of the equation we obtain:

Hence we get two points on the number line.

x=8   and x= -8.

These are the discrete values we did not get any interval of the solution.

step-by-step explanation:

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)
