A student is attempting to solve the equation below for the variable x. Which of the statements below best applies to the mathematical work shown? Given \sqrt(x+5)=1 , I square both sides, which gives me the equation x + 5 = 1. I can then solve for x, yielding x = –4 as my final answer. A. The student did not correctly square both sides of the equation. B. The student did not properly isolate the variable after squaring both sides of the equation. C. The student omitted a negative solution to the equation. D. The mathematical work is correct.

300

step-by-step explanation:

28-600w < 300

28-600w > 300

600-28w < 300

600-28w > 300

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)
