Answer:
2 & 3
Step-by-step explanation:
Pythagorean Theorem is 
.
If the values given in each option satisfy the theorem, the sides will make a right triangle.
<h3>For Option One:</h3>
The sides would not make a right triangle.
<h3>For Option Two:</h3>
The sides would make a right triangle.
<h3>For Option Three:</h3>
The sides would make a right triangle.
<h3>For Option Four:</h3>
The sides would not make a right triangle.
The correct answer should be options two and three.
Answer:
Step-by-step explanation:
Given expression:
To simplify the expression, we will use the formula (a - b)² = a² - 2ab + b².
[Where "a and b" are the first and second term in (a - b)²]
In this case, the first term of (2x - 12)² is "2x" and the second term is "12".
![\rightarrowtail (2x)^{2} - 2(2x)(12) + (12)^{2} \ \ \ \ \ \ \ \ \ \ \ \ \ \ [\small\text{First term = a = 2x; Second term = b = 12]}](https://tex.z-dn.net/?f=%5Crightarrowtail%20%282x%29%5E%7B2%7D%20-%202%282x%29%2812%29%20%2B%20%2812%29%5E%7B2%7D%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%5C%20%20%5B%5Csmall%5Ctext%7BFirst%20term%20%3D%20a%20%3D%202x%3B%20Second%20term%20%3D%20b%20%3D%2012%5D%7D)
Now, simplify the expression.
Answer:
c = 22
Step-by-step explanation:
x^2 + c = 103 so if x is either + or - 9, x^2 = 81 so...
81 + c = 103
c = 22
we know that
The unit rate is $0.65 per foot
so
To find out the cost, multiply the unit rate by the length of the rope
so
0.65*(10.8)=$7.02
therefore
<h2>The cost is $7.02</h2>
