Answer: Factorization of 6x + 120 = 6(x+20)
Factors = 6 and x+20
Step-by-step explanation:
Given: The expression 6x + 120 represents the total amount in the account after 6 months.
We need to factor the expression 6x + 120
We can write this as
6 x + 6 (20)
Common factor = 6 in both terms
So, 6 x + 6 (20) = 6(x+20)
Hence, Factorization of 6x + 120 = 6(x+20)
Expand the square: 4(x-11)^ =25
4(x-11)(x-11)=25
Distribute : 4(x-11)(x-11)=25
4(x(x-11)-11(x-11))=25
Distribute: 4(x(x-11)-11(x-11))=25
4(x^-11x-11(x-11))=25
Solution: x=17/2
x=27/2

Answer:
Step-by-step explanation:
The scientist can use only the angle x and the distance y to calculate the distance between the Earth and the Sun using the cosine function.The cosine of an angle is equal to the ratio of the length of the adjacent side and the length of the hypotenuse. In equation form:cos x = BC / ySolving for BCBC = y cos xBC is the distance between the Earth and the Sun
