So I'm not 100% on this, but I believe that first you need to combine like terms. The 4x and the -2x make 2x and distribute the 2 so you get 2x+1. That all equals 2x+5=2x+2. You need to get the variable by themselves so I will minus the 2. You then get 2x+3=2x. You then need to minus the 2x, which makes 0. So the answer is 3=0, or undefined. Is that about what you guys are working on? Have you learned about undefined?
Answer:
Step-by-step explanation:
= 
We need a common denominator before we can add.
+ 
means the same thing as
- =

Step-by-step explanation:
Using the chain rule
Given
y = f(g(x)), then
= f'(g(x)) × g'(x) ← chain rule
and the standard derivatives
(
x ) = 
, (lnx) = 
(a)
Given
y = 
= 
× (
= × 
× (1 + x)
= × 
× 1
= 
= 
(b)
Given
y = ln sinx
= 
× (sinx)
= × cosx
= 
= cotx

1. Right angled triangle , scalene triangle
2. isosceles triangle, obtuse angled triangle
3. equilateral triangle
4. right angled triangle, isosceles triangle
5. scalene triangle, obtuse angled triangle
6. scalene triangle, acute angled triangle
4x + 7x = 33
11x = 33
x = 3
4x = 4(3) = 12
7x = 7(3) = 21
12 and 21 are how you split 33 in to a ratio of 4 to 7.
