Width = W
Length = 12W - 1
Perimeter = 2L + 2W = 37
In the perimeter equation substitute the length equation in for L to get the equation in terms of W
2L + 2W = 37
2(12W - 1) + 2w = 37
Distribute
2(12W - 1) + 2w = 37
24W - 2 + 2w = 37
26W = 39
W = 3/2 = 1.5
Width = 1.5
Lastly, solve for length
L = 12W - 1
L = (12 • 1.5) - 1
L = 18 - 1
L = 17
Length = 17
The last one is the correct one.
Answer: None of the above
Step-by-step explanation:
The correct answer for this question would be the last option. The complete factor of 25x^2 – 36 is <span>(5x – 6)(5x + 6). To check, multiply both values. 5x times 5x is 25x^2, and -6 times 6 is -36. Which gives us 25x^2-36. Hope this answers your question. Let me know if you need more help next time.</span>
Answer:
60 degrees
Step-by-step explanation:
You can use this triangle in a Pythagorean Theory. It means that angles inside are 90 degrees, 60 degrees, and 30 degrees. It is bigger than angle E so it have to be 60 degrees.
