Answer:
4
Step-by-step explanation:
coefficient is the number next to the variable.
ANSWER:
Let width be x, then length be 2x – 2
Now, Area of rectangle = L × B
- x(2x – 2) = 40
- 2x² – 2x – 40 = 0
- 2(x² – x – 20) = 0
- x² – x – 20
- x² –5x + 4x – 20 = 0
- x(x – 5) + 4(x – 5) = 0
- (x + 4)(x – 5) = 0
- x = – 4; 5
Hence, width can't be negative.
So width = 5in.
And Length = 2 × 5 – 2
So, <u>Correct choice</u> - [D] Length is 8 in, Width is 5 in.

Step-by-step explanation:
5(0)-3(-4)=12 that simply's to 0+12=12
its no subtraction sign cause cant have a double negative
Answer:
50 is the old value and 23 is the new value. In this case we have a negative change (decrease) of -54 percent because the new value is smaller than the old value. Using this tool you can find the percent decrease for any value.
Hello!
To understand this question we first need to find some common measurements to make this math easier.
One day is equal to 24 hours.
One hour is equal 60 minutes.
One day in hours would be equal to 24 · 60, or 1440 minutes.
1440 is equal to 100% of our day.
To find 50% we can then divide that value in half to get 720 minutes.
Half of that value, or 25%, is equal to 360 minutes.
