add or subtract the polynomials
(7x + 11y) - (5x + 6y)

(13x + 12y) - (6x + 2y)

(8x + 8y) - (4x - 2y)

Answers

Answer 1

Answer:

7xy + 6y + 6xy is a polynomial who’s like terms are 7xy and 6xy. Therefore, this polynomial can be simplified by combining like terms as 7xy +6xy +6y = 13xy + y. When combining like terms, we only add or subtract the coefficients of the identical variables.

On the other hand, unlike terms are terms which are not identical in terms of either variables or exponents.

For example, an expression 4x + 9y2, contain unlike terms because variable x and y are different and are not raised to the same power.

Answer 2

Answer:

1.

7x+11y-(5x+6y)

7x+11y-5x-6y

2x+5y

2.

13x+12y-(6x+2y)

13x+12y-6x-2y

7x+10y

3.

8x+8y-(4x-2y)

8x+8y-4x+8y

4x+16y

A triangle has side lengths of (6v+2) centimeters, (6v+5) centimeters, and (3w-2) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?

ILL GIVE YOU BRAINS :)

Answers

The expression that represents the perimeter is [tex]12v + 3w + 5[/tex]

Definition of Perimeter

      The perimeter of a figure is defined as the total length of the outer boundary of that figure. It is the sum of length of each side of a figure.

Calculation of Perimeter of given triangle:

Given,

The triangle has sides of length [tex](6v+2)cm, (6v+5)cm[/tex] and [tex](3w-2) cm[/tex].

The perimeter can be calculated by adding the sides.

⇒ [tex](6v+2) + (6v+5) + (3w-2)[/tex]

Now, like terms and constants can be written together

⇒ [tex]6v + 6v + 3w + 2 + 5 - 2[/tex]

⇒ [tex]12v + 3w + 5[/tex]

Hence, the expression that represents the perimeter of given triangle is  [tex]12v + 3w + 5[/tex].

B.
$615.25

C.
$690.00

D.
$650.50

Answers

The answer would be A)$679.80
The reason for this is let’s start with the mark up of 10%. Meaning we will add the result of the markup to our first number We would take 1000*.1 which would give us 100.
Add that to the original to give you $1,100.
Then the item was discounted for 40% meaning we take away the result of 1,100*.4 which equals 440. 1100-440=660.
Then taxes are added on to the total so you would do 660*.03 which would give you 19.8
660+19.8 gives you$679.80.
the answer is A i hope this helped

so C (10.7)

Answer:

2πr=c, Perimeter, or Circumference is what we are looking for, and this is the formula.

so we need to figure out 2 x 3.14 x radius:1.7 = Perimeter or Circumference

2 x 3.14 = 6.28

6.28 x 1.7 = 10.28
