Synthetic division (12x^4+5x^3+3x^2-5)/(x+1)

Mathematics
1 answer:
Troyanec [42]3 years ago
4 0

Since you have exponents this is what you end up getting.

I only used the calculator for the multiplying. (Also I used * for multiplying)

(12x^4+5x^3+3x^2-5)/(x+1)

(12x*x*x*x+5x*x*x+3x*x-5)/(x+1)

(12+5+3-5)/(x+1)

(15)/(x+1)

You divide.

You get 15.

Now you add up the x's.

15x^9 plus another x because of the one in the other parentheses.

Answer: 15x^10

The equation a = 26w gives the area of a (in square feet) of a rectangle dance floor with a width of w feet help please this is
Alexeev081 [22]

Answer:

<em>26ft</em>

Step-by-step explanation:

<em>Complete Question:</em>

<em>The equation a = 26w gives the area of a (in square feet) of a rectangle dance floor with a width of w feet. Find its length</em>

<em></em>

Formula for calculating the area of a rectangle is expressed as shown;

Area of a rectangle = Length * Width

Given the equation a = 26w that gives the area of a rectangle

On comparing with the formula;

Length * Width = 26w

Length = 26ft (by comparison)

<em>Hence the length of the rectangle is 26ft</em>

(HELP ASAP!)<br>Which postulate or theorem proves △HJZ∼△WJR ?
Tomtit [17]

Answer:

SAS Similarity Theorem

Step-by-step explanation:

we know that

<u>SAS Similarity Theorem</u>: States that if two sides in one triangle are proportional to two sides in another triangle and the included angle in both are congruent, then the two triangles are similar

In this problem

∠HJZ=∠RJW ----> by vertical angles

and

WJ/HJ=JR/JZ

substitute the values

8/4=6/3

2=2 ----> is true

so

Two sides of triangle HJZ are proportional with the two corresponding sides of triangle WJR and the included angle is congruent

therefore

Triangles are similar by SAS Similarity Theorem
