X=4 this is because 4 times (x+1)-5=11 the 1x then just turns to x because you can’t have a 1 next to x when it’s just one x.
4*(x+1)-5=11
4(x)-5=11
4x-5=11
+5=11

Help! Please! Thanks
Illusion [34]

Answer:

C. 3 (t+2)

Step-by-step explanation:

First, for the top fraction, simplify it:

4(t^2-4)/8=4(t+2)(t-2)/8

Now, flip the denominator and multiply the top and bottom fractions:

4(t+2)(t-2)/8 * 6/t-2

You can cancel the (t-2) terms so you get:

4(t+2) *6/8

Reduce the 6/8 to 3/4 so you get:

4(t+2)*3/4

Now cancel the 4's:

3(t+2)  Your answer is C.
