Answer: See explanation
Step-by-step explanation:
Area of a rectangle = length × width
From the question, we are informed that the length of a rectangle is 8 feet, and its area is less than 168 square feet.
Therefore, the width will be calculated thus:
Length × Width < 168
8 × Width < 168
8W < 168
W < 168/8
W < 21
The width is less than 21 feet
So here are the solutions to your given questions above:
For question 1:
Based on the given values, let us try to expand it.
And the result would be -2x-6 = -2x-6.
This makes the solution would be all real numbers. When we say the solution is all real numbers, i<span>solate the x term by subtracting x from both sides and you end up getting "2=2", which makes it a true statement, and therefore, the solution of the equation is all real numbers.
For question 2:
Since the equation is already given and x represents the number of people who joined the site that month, let us solve for x.
</span><span>x = 0.8x + 72
x - 0.8x = 72
0.2x = 72
x = 72/0.2 = 360
</span>The number of people who became a member of that month is 360 in total.
Since 80% of it are ages 30 to 40 years old, we are going to find 80% of 360 and that would be 288. So the answer is the second option.
