Hey guys! i need with question 3.

So firstly, you want to multiply both sides by (x-2)(x+2) since it is the LCM, or lowest common multiplier. Your equation will look like this:

Next, you can cancel out the denominators on 3/x+2 and 4/x-2 on the left side:

Next, foil:

Next, combine like terms:

Next, add x + 14 on both sides:

Next, replace x with -5x + 6x:

Next, factor 5x^2-5x and 6x-6 separately. Make sure that both factors have the same quantity within the parentheses:

With this, we can rewrite it as From here, we solve for x in (5x+6) and (x-1) separately and setting them to zero.

In short, x = -1.2, 1.

f(x) is going down by 4

step-by-step explanation:

(its either that or its going left by 4)

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
