Answer:
x = 3.3 and -0.3
Step-by-step explanation:
Given the expression
1/x-4 + x/x-2=2/x^2-6x+8
Find the LCM
x-2+x(x-4)/(x-4)(x-2) = 2/x^2-6x+8
Since the denominator, are the same they cancels out
x +1 + x(x-4) = 2
x+1 + x²-4x = 2
x²-3x + 1 - 2 = 0
x² - 3x - 1 = 0
Factorize
x =3±√9+4/2
x =3±√13/2
x = 3±3.6/2
x= 6.6/2 and -0.6/2
x = 3.3 and -0.3

Step-by-step explanation:
I disagree because if both number are the same so how would they be different heights if the both triangles have the same numbers 7,5,5 and 7,5,5 so none are the same height.
Answer:
Step-by-step explanation:
Initial amount deposited in the certificate of deposit is $15000 This means that the principal so
P = 15000
It was compounded quarterly. This means that it was compounded 4 times in a year. So
n = 4
The rate at which the principal was compounded is 7.5%. So
r = 7.5/100 = 0.075
It was compounded for 2 years. So
t = 2
The formula for compound interest is
A = P(1+r/n)^nt
A = total amount in the account at the end of t years. Therefore
A = 15000 (1+0.075/4)^4×2
A = 15000(1.01875)^8 = $17403
The interest would be
17403 - 15000 = $2403
