Answer:
3x+1/2x
Step-by-step explanation:
When simplifying algebraic expressions, we should first factorise each term fully to find any common factors. First we should factorise the numerator where 3x2-8x-3 factorises to (3x+1)(x-3). Next, we should factorise the denominator where 2x2-6x factorises to 2x(x-3). Now we see that (x-3) is the highest common factor of both the numerator and denominator, hence we can "cancel" the (x-3) term from both the numerator and denominator. Therefore, the expression simplifies fully to (3x+1)/(2x)
Answer:
X= 140
Step-by-step explanation:
f(x) = x3 – 4x² - 6x – 32 at x = 6
(6)(6)(6) -4²=72
-6(6)-32= -68
72+68=140
Answer:
43.71428571
Step-by-step explanation:
First, convert 7 2/7 into an improper fraction: 51/7
Second, multiply 51/7 by 5: 255/7
Third, add 255/7 and 51/7 to get 306/7
306/7 = 43.71428571
Answer:
x = 4.5
Step-by-step explanation:
14 = 8/3x + 2
12 = 8/3x
36 = 8x
x = 4.5
