Answer: The value of y is 39.6 when x = 11 and the required expression is y(11) = 39.6
Step-by-step explanation:
Since we have given that
y varies directly as x.
If y = 18, when x = 5.
So, we need to find the value of y when x is 11.
According to question, we get that

Hence, the value of y is 39.6 when x = 11 and the required expression is y(11) = 39.6
That would be a scalene triangle, because all three sides are different measurements. Equilateral means all 3 sides are equal and isocelese means that 2 sides are equal. Therefore it would have to be scalene
Answer:
0 degrees?
Step-by-step explanation:
It looks perfectly even to me
Xd = y(L-d) then divide by "y"
xd/y = L - d then add "d"
xd/y + d = L
X+y = 4, -----> y=4 - x
x² +(4-x)² =16
x² +16-2*4x+x² =16
2x² - 8x = 0
x(2x-8) = 0
2x-4=0, 2x=8, x=4
x=0 or x=4
If x=0, y=4-x=4-0=4.
If x=4, y= 4-x=4-4=0.
(0,4) or (4,0)
Check
x² +y² =16
For (0,4)
0²+4² =16
16 =16 True
For (4,0)
4² +0²=16
16=16 True
Answer (0, 4) and (4,0).
