angle LMN and L are corresponding so they are equal to each other
x = 3x - 70
...subtract 3x
-2x = -70
...divide by -2
x = 35
...angle LMN: 3(35) - 70 = 35
answer is C
Answer:A
Step-by-step explanation:
I just took the test
False , The cross products property
Let's assume the middle number is

then the smallest number is

the greatest number is

so the sum of the three number would be

and it equals 45
now we have an equation

then we solve it


, which means the middle number equals 15
so the greatest number would be

17 is the greatest number
First we use product rule
y=x^2lnx
dy/dx = x^2 d/dx (lnx) + lnx d/dx (x^2)
dy/dx = x^2 (1/x) + lnx (2x)
dy/dx = x + 2xlnx
now taking second derivative:
d2y/dx2 = 1 + 2[x (1/x) + lnx (1)]
d2y/dx2 = 1 + 2[1+lnx]
1+2+2lnx
3+2lnx is the answer
