Answer:

1. Determine whether you have a linear polynomial. A linear polynomial is a polynomial of the first degree. This means that no variable will have an exponent greater than one. Because this is a first-degree polynomial, it will have exactly one real root, or solution

2. Set the equation to equal zero. This is a necessary step for solving all polynomials.

3. Isolate the variable term. To do this, add or subtract the constant from both sides of the equation. To do this, add or subtract the constant from both sides of the equation. A constant is a term without a variable

4. Solve for the variable.Usually you will need to divide each side of the equation by the coefficient. This will give you the root, or solution, to your polynomial.

Step-by-step explanation:

For Example:

5x+2=0

5x+2-2=-2

5x+-2

(1/5) 5x=1/5-2 (cross out the five on the fraction and the equation and move the 1/5 to the other side of the equation) so that it just looks like this 5x=1/5-2

x=2/5

Answer: The equation is true

Step-by-step explanation:

Since x=3 and y= 5

Substitute the values for x and y

(-4c? + 7cd + 8d) + (-3d + 8c2 + 4cd)

Alex

Answer: 4c2 + 11cd + 5d

Step-by-step explanation:

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "c2" was replaced by "c^2". 1 more similar replacement(s).

Step by step solution :

Step 1 :

Equation at the end of step 1 :

(((0-(4•(c2)))+7cd)+8d)+((-3d+23c2)+4cd)

Step 2 :

Equation at the end of step 2 :

(((0 - 22c2) + 7cd) + 8d) + (8c2 + 4cd - 3d)

Step 3 :

Trying to factor a multi variable polynomial :

3.1 Factoring 4c2 + 11cd + 5d

Try to factor this multi-variable trinomial using trial and error

1st 3 0.80 2.40 
2nd 2.40 0.80 1.92 
3rd 1.92 0.80 1.54 
4th 1.54 0.80 1.23 
5th 1.23 0.80 0.98 
6th 0.98 0.80 0.79 
7th 0.79 0.80 0.63 
8th 0.63 0.80 0.50 
9th 0.50 0.80 0.40 
10th 0.40 0.80 0.32
total: 13.39

13.39 rounded to 13.40 is the sum of the length of string after 10 throws.

Based on the table: I generated the formula:

f(x) = 3 × 0.80ˣ

where the exponent x represents the number of throws.

A rectangular athletic field is twice as long as it is wide. if the perimeter of the athletic field is 192 yards, what are its

qaws [65]

P = 2(L + W)
P = 192
L = 2W

192 = 2(2W + W)
192 = 2(3W)
192 = 6W
192/6 = W
32 = W <=== the width is 32 yards

L = 2W
L = 2(32)
L = 64 <=== the length is 64 yards
