Explanation:
-40 - 6m + 1 = - 2
- Simplify Both Sides Of The Equation
−40 − 6m + 1 = −2
−40 + −6m + 1 = −2
(−6m) + (−40 + 1) = −2 (Combine Like Terms)
−6m + −39 = −2
= −6m − 39 = −2
- Add 39 To Both Sides
−6m − 39 + 39 = −2 + 39
−6m = 37
- Divide Both Sides By -6
-6m / -6 = 37 / -6
- Simplify

Answer:
Step-by-step explanation:
The formula that is used to calculate the area of a rectangle is:
Where "l" is the lenght and "w" is the width.
You know that the area of that rectangle is:
And, according to the exercise, its lenght is 7 more than its width; then:
Then, you can make the corresponding substitution into the formula :
Simplify:
Factor the equation. Find two numbers whose sum is 7 and whose product is -744. These are 31 and -24.
Then, you get:
The width of the rectangle is the positive value:
Then, the lenght is:
