Subtract.<br> (2x^2+4x−8)−(4x^2−x+1)

stiks02 [169]

2x + 6 = 4x - 2
Simplifying
2x + 6 = 4x + -2

Reorder the terms:
6 + 2x = 4x + -2

Reorder the terms:
6 + 2x = -2 + 4x

Solving
6 + 2x = -2 + 4x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4x' to each side of the equation.
6 + 2x + -4x = -2 + 4x + -4x

Combine like terms: 2x + -4x = -2x
6 + -2x = -2 + 4x + -4x

Combine like terms: 4x + -4x = 0
6 + -2x = -2 + 0
6 + -2x = -2

Add '-6' to each side of the equation.
6 + -6 + -2x = -2 + -6

Combine like terms: 6 + -6 = 0
0 + -2x = -2 + -6
-2x = -2 + -6

Combine like terms: -2 + -6 = -8
-2x = -8

Divide each side by '-2'.
x = 4

Simplifying
x = 4

Solve for x: 4(3x - 5) = 7(2x + 3).

Charra [1.4K]

X= -41/2

12x-20=14x+21
12x-20+20=14x+21+20
12x=14x+41
12x-14x=14x+41-14x
-2x=41
-2x/-2=41/-2
x=-41/2

Trace needs a new carpet for her house the living are is an open floor plan of a dining room 6 feet c 4 feet sitting area 10 fee

hram777 [196]

Answer:

199 square feet

Step-by-step explanation:

Given:

Trace needs a new carpet for her house.

Dimension of dining room = 6 feet by 4 feet.

Dimension of sitting area = 10 feet by 15 feet.

Dimension of breakfast nook = 5 feet by 5 feet.

<u>Question asked:</u>

How many square feet of carpet does she need ?

<u>Solution:</u>

<em>First of all we will calculate the area of each part of the house and then add up.</em>

<em /> $Area \ of \ dining\ room=length\times width$

$=6\times4\\ \\ =24\ square\ feet$

$Area \ of \ sitting\ part=length\times width$

$=15\times10\\ \\ =150\ square\ feet$

$Area \ of \ breakfast\ nook=(side)^{2}$

$=5^{2} =25\ square\ feet$

Total carpet needed will be needed = For dining + For sitting area + For breakfast nook

= 24 + 150 + 25

= 199 square feet

Therefore, she needs 199 square feet of a new carpet for her house.
