What is 5(x + 6)+11 =25 3x
1 answer:
Answer:
x=
Step-by-step explanation:
5(x+6)+11=25
Use the distributive property to multiply 5 by x+6.
5x+30+11=25
Add 30 and 11 to get 41.
5x+41=25
Subtract 41 from both sides.
5x=25−41
Subtract 41 from 25 to get −16.
5x=−16
Divide both sides by 5.
x=-16/5
Fraction -16/5 can be rewritten as -16/5 by extracting the negative sign.
x =

Answer:
x = π/3, x = 5π/3, x = 4π/3
Step-by-step explanation:
Let's split the given equation (2cosx-1)(2sinx+√3 ) = 0 into two parts, and solve each separately. These parts would be 2cos(x) - 1 = 0, and 2sin(x) + √3 = 0.
Remember that the general solutions for cos(x) = 1/2 are x = π/3 + 2πn and x = 5π/3 + 2πn. In this case we are given the interval 0 ≤ x ≤2π, and therefore x = π/3, and x = 5π/3.
Similarly:
The general solutions for sin(x) = - √3/2 are x = 4π/3 + 2πn and x = 5π/3 + 2πn. Therefore x = 4π/3 and x = 5π/3 in this case.
So we have x = π/3, x = 5π/3, and x = 4π/3 as our solutions.
