Answer:
x = 5 or 1
Step-by-step explanation:
Square both sides to get
x^2 - 6x + 9 = 4 now subtract four from both sides
x^2 -6x+5 = 0 now factor ( or use quadratic formula)
(x-5)(x-1) = 0 so x = 5 or 1
Answer:
5-x
Step-by-step explanation:
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
• tanx = 
• sin²x + cos²x = 1 ⇒ sin²x = 1 - cos²x
Consider the left side
= 
- 
= 1 - cos²x
= sin²x = right side ⇒ verified
Answer:
Distribute, subtract, additon,divide
Step-by-step explanation:
4(x-7)=2x-6 to get the second problem you distribute the 4 to the 7 and x
4x-28=2x-6 subtract the 2x from 4x
2x-28=-6 then u add the 28 to the negative 6
2x=22 divide
x=11
So.... You would get your problem out of the numbers 10,6,7 you would multiply and get 10*6*7=420 so 420 would be the answer if that's what your looking for!!
Hope i helped if i did please make me Brainiest
