To solve this problem, you'll want to substitute the variables for the values you are given and follow the order of operations. Let's substitute first, shall we?

xz becomes 4 times 1.
4y becomes 4 times 2.
2z becomes 2 times 1.
Now that we have everything substituted in, we have our new equation.
4*1(4*2 - 2*1) With the asterisks representing the multiplication sign.
Now, solving those first easy problems as the first step, we get..
4(8-2)
Remember to follow order of operations! Do the problem in the parentheses first, 8-2.
Now we have 4(6).
Assuming the problem is exactly how you wrote it and you are supposed to multiply the two numbers, your answer is 24.

[(7+3)x5-4](divided by) 2+3<br> SHOW ALL WORK WILL MARK BRAINLIEST

Nesterboy [21]

Answer:

Step-by-step explanation:

[(7+3)5-4]/2+3

-To solve this equation you have to use PEMDAS

P- Parentheses

E- Exponents

M- Multiplication

D- Division

A- Addition

S- Subtraction-

- With MD and AS you work left to right of the equation since they are in the same spot. (PE[MD][AS])

Step 1) [(10)5-4]/2+3

- First you do "P," parentheses, so you add 7+3=10

Step 2) [50-4]/2+3

- Next you do "M," multiplication, and multiply 10x5=50

Step 3) [46]/2+3

- Then you do "S," subtraction, and subtract 50-4=46

(FYI: Steps 1-3 were still in the parentheses. We had to start with the parentheses in the parentheses, work PEMDAS, and now we are out of the parentheses and have to work PEMDAS on the rest of the problem.)

Step 4) 23+3

- Now we do "D," division, and divide 46/2=23

Step 5) 23+3=6

- Finally we do "A," addition, and add 23+3=26 so the answer is 26

(FYI: "/" means division)

Drag the correct factors to the expression. Not all factors will be used. Use synthetic division to find all the factors of this

fiasKO [112]

The factors are therefore; (4x – 3), (x + 3) and (x – 1)

<h3>What is a polynomial?</h3>

A polynomial is is a function that contains an algebraic term which is raised to a particular power.

If it is raised to power 1 it is linear
If it is raised to power 2 it is quadratic
If its is raised to power 3 it is cubic
If it i raised to power 3 it is quartic

Now we have;

4x³ + 5x² – 18x + 9

Thus we can write;

4x³ – 3x² + 8x² – 6x – 12x + 9

Using the factors;

x²(4x – 3) + 2x(4x² – 3) – 3(4x – 3)

Therefore;

(4x – 3)(x² + 2x– 3)

(4x – 3)(x² + 3x – x – 3)

(4x – 3)(x + 3)(x – 1)

The factors are therefore; (4x – 3), (x + 3) and (x – 1)
