Answer:

The hierarchy is starting by the parenthesis, followed by any multiplications or divisions and ultimately the additions and subtractions.

Step-by-step explanation:

First operation

1. (1/5+1/2)=(2/10+5/10)= 7/10

2. (7/10)^2= 49/100

4. (49/100) + (3/50)= (49/100 + 6/100) = 55/100

Second operation

We start by the numerator

1. (18 - 4^2 +2) = 18 - 16 +2 = 4

2. 4*2 = 8

Following with denominator

1. 1/4*12= 1/48

When we divide a number by a fraction we have to make use of the following rule (a/b)/(c/d)=(a*d)/(b*c)

Hence: (8)/(1/48) = 8*48 / 1 = 8*48 =384

If : f(x)=x^2, g(x)=x-1. Find (f×g)(x).<br>

kramer

Answer:

$\boxed{ f\cdot{g}(x) = x {}^{3} - x {}^{2}}$

Step by step explanation:

Given that,

$f(x) = {x}^{2}$

$g(x) = x - 1$

Solution:

Solving for (f•g)(x):

$= f(x) \cdot g(x)$

Now substitute the given values.

$= x {}^{2} \cdot(x - 1)$

$= x {}^{2} (x - 1)$

Apply distributive property:

$= (x ^{2} \cdot x) - x {}^{2} \cdot 1$

$\boxed{ f\cdot{g}(x) = x {}^{3} - x {}^{2}}$

Hence,f•g(x) will be $x {}^{3} - x {}^{2}$ .

What is the answer to 0 > 3x - 3 - 6?

swat32

Answer:

3 = x

Step-by-step explanation:

0 > 3x - 3 - 6

You want to group up the -3 and -6 first

0 > 3x - 9

Then you want to add 9 to each side to cancel out the negative 9 on one side.

0 > 3x - 9

+9 +9

9 > 3x

Now you just divide by 3 on each side

$\frac{9 = 3x}{3}$

3 = x
