Answer:
C. 20 feet
Step-by-step explanation:
Let x = width
Let y = length
If the length is at least 10 feet longer than the width:
⇒ x + 10 ≤ y
⇒ x ≤ y - 10
If the perimeter is to be no more than 100 ft:
⇒ 2x + 2y ≤ 100
⇒ x + y ≤ 50
⇒ x ≤ 50 - y
Equate the equations for x and solve for y:
⇒ y - 10 = 50 - y
⇒ 2y = 60
⇒ y = 30
Substitute found value of y into one of the inequalities for x:
⇒ x ≤ 30 - 10
⇒ x ≤ 20
Therefore, the maximum possible width of the fence is 20 feet.
So to find x we need to add both HI and IJ - which we know equals 7:
Then we need to combine like terms:
And then set equal to 0:
Then we can factor:
So then when we set each term equal to 0 individually and solve for x we get: x = -5 and x = -2.
So we have these two values - we need to test which one is correct. So if we go back to the HI segment, let's try plugging in x = -5:
This gives us a negative number, which we know that length cannot be negative. Let's try x = -2:
This gives us a positive length and therefore we can keep this value.
So the answer is: x = -2.
Answer:
Step-by-step explanation:
Because of similar triangles formed we can say
h/12=5.5/2
h=66/2
h=33ft
