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
Answer:
x =2
2 in, 6 in, 1 in
Step-by-step explanation:
Answer:
9^5is the answer.
Step-by-step explanation:
(i)9^6×9^3=9^9 when we multiply we will add the power.
(ii) 9^9÷9^4= 9^5 when we divide we will subtract the power.
Answer:
m∠C = 90°
Step-by-step explanation:
Triangle BDC is a right triangle with the measure of angle D = 90°
By applying Cosine rule in the given triangle,
Since, Cosine of any angle in a right triangle is a ratio of Its adjacent side and Hypotenuse (Opposite side of the right angle)
CosC =
CosC =
CosC =
C = 28.955
C = 29°
Therefore, m∠C = 29° will be the answer.
