Value of x is -1
The correct first step to solving the inequality is distributing the -4 into the para thesis
Answer:
11.61895003862225
Step-by-step explanation:
Let "a", "b" and "с" be sides of the triangle ("с" is the longest side). The triangle will be right if a² + b² = c²
<span>a. 13 35 37
13</span>² + 35² = 1394 and 37² = 1369
1394 ≠ 369
<span>b. 6 9 10
</span>6² + 9² = 117 and 10² = 100
117 ≠ 100
<span>c. 5 12 13
</span>5² + 12² = 169 and 13² = 169
169 = 169 ← <span> right triangle
</span>d. 9 40 42
9² + 40² = 1681 and 42² = 1764
1681 ≠ 1784
The answer is <span>c. 5 12 13</span>
We know that the fence is 52 <em>feet</em> long, but since it's sold in yards, we need to somehow convert feet to yards.
First, we need to find a little something called a conversion factor. Basically, we need to see what we can do to get from <em>one foot</em> to <em>one yard</em>.
Well, how many feet are there in a yard? <em><u>3.</u></em><u /><u /> So now we know that <em><u>one foot is 1/3 of a yard.</u>
</em>
So to convert 52ft to yards, we need to divide by 3. What's 52 divided by 3?
17.33.
Now we just need to multiply that by 10.99 so that we can find out the cost.
We get 190.45. That's your answer!
It all cost <em>$190.45
