4x+12=1x+60
4x+12=x+60 Move terms
4x-x=60-12 collect the like terms
Subtract
3x=48
Divide both sides by 3
X=16
Answer:
See below
Step-by-step explanation:
In the second step there should be (1 - cot x) instead of (1 + cot x)
(1 + tan x) [1 + cot(-x)]
= (1 + tan x) (1 - cot x)
= 1 - cot x + tan x - tan x cot x
= 1 - cot x + tan x - 1
= tan x - cot x
This question can go either way:
100-8=92 dollars back
Or
100 divided by 4+8= 33 dollars left

A. 6*3*4=12*2*3 = 72
Surface area =
2(6*3) + 2(3*4) + 2(6*4) not equal to 2(12*2) + 2(12*3) + 2*(2*3)
