6/x-8=2/x+6 how do i solve this

lutik1710 [3]

6/(x-8)=2/(x+6)
times both sides by (x-8)(x+6)
6(x+6)=2(x-8)
distribute
6x+36=2x-16
minus 2x both sides
4x+36=-16
miinus 36 both sides
4x=-52
divide both sides by 4
x=-13

Factor 7w2−175.(1 point) −7(w−25) 7(w−25) 7(w−5)(w+5) 7(w−5)(w−5)

Nutka1998 [239]

Answer:

7(w + 5)(w -5)

Step-by-step explanation:

a² - b² = (a + b)(a - b)

7w² - 175 = 7w² - 7*25

= 7(w² - 25)

= 7(w² - 5²)

= 7(w + 5)(w -5)

The answer is unreasonable because the value of x is between 2 and 3.The error is : she did not introducing logs in solving the equation.

Step-by-step explanation:

The question is $7^x=95$

Here answers is unreasonable because, she can test with powers of seven like;

7²=49

7³=343

So this means the value of x lies between 2 and 3, so here answer 11.71 is unreasonable

b) In this case, to solve the equation, introduce logs both sides

$7^x=95$

$log7^x=log95\\\\\\xlog7=log95\\\\\\x=\frac{log95}{log7} \\\\\\x=2.340$
