You are correct! Good job
Answer:
X=1.132589
Step-by-step explanation:
If im correct the answer would be x=1.132589
3
x2−1
−2(x+3)=
5
x+1
3
(x+1)(x−1)
+−2x−6=
5
x+1
Multiply all terms by (x+1)(x-1) and cancel:
3+(−2x−6)(x+1)(x−1)=5(x−1)
−2x3−6x2+2x+9=5x−5(Simplify both sides of the equation)
−2x3−6x2+2x+9−(5x−5)=5x−5−(5x−5)(Subtract 5x-5 from both sides)
−2x3−6x2−3x+14=0
(Use cubic formula)
x=1.132589

Answer:
0.95
Step-by-step explanation:
Let's convert this into a fraction that has a denominator of 100. In order to do so, we need to multiply the numerator and denominator both by 5 (because 20 * 5 = 100):
So, we have 95/100, which is technically 95 divided by 100. Whenever we divide something by a power of 10, like , where n is any integer, we move the decimal point of the dividend n places to the left.
Here, we have 100, which is , so we want to move the decimal point of 95 (which equals 95.0) 2 places to the left:
0.95
