Answer:
121 x 59 (Dimensions)
Step-by-step explanation:
6x + 6 = 360
Take away 6 from both sides
6x = 354
Divide both sides by 6
x = 59
The length is 2x + 3 because it says 3 more than double the width (lenght is x). You have 2 widths and 2 lengths. The two widths are both x (2x). The two lengths are both 2x + 3 (4x + 6). 2x + 4x + 6 = 6x + 6.
Now input 59 for x
2(59) + 3 = 121
x = 59
Check Your Answer
121 is just one length and 59 is just one width, so you have to multiply both sides by 2 because you have 2 widths and 2 lengths.
121 x 2 = 242
59 x 2 = 118
242 + 118 = 360
It's between 101 and 199.
5 less than 10 is 5.
2 more than 5 is 7
My guess is 157
Answer:
-2 - 5 = -7
Step-by-step explanation:
<u>Choice A: </u><u />
<u>Choice B: </u>9, 40, 41
<u>Choice C: </u>
Answer:
(B)9, 40, 41
Step-by-step explanation:
To check if the sides form a right triangle, you check to see if they satisfy the Pythagorean theorem.
Note that the longest side length is always the hypotenuse.
<u>Choice A: </u><u />
Now,
Therefore:
These side lengths form an equilateral triangle. They do not satisfy the theorem.
<u>Choice B: </u>9, 40, 41
The longest side length is 41.
Therefore:
These side lengths form a right triangle.
<u>Choice C: </u>
Therefore, the longest side length is
These side lengths do not form a right triangle.
