Answer:

x= plus or minus square root of 19 -4

Step-by-step explanation:

x^2+8x ___=3

take half of your b term (8) and then multiply by two and add or subtract it to both sides

x^2+8x+16=3+16

then combine like terms

x^2+8x+16=19

then factor your quadratic equation

(x+4)^2=19

now solve for x

take the square root of (x+4)^2 to get rid of the ^2

you then also have to square the 19 because what you do to one side you have to do to the other

(x+4)= square root of 19

subtract 4 from both sides

x= plus or minus square root of 19 -4

Answer:

Step-by-step explanation:

Divide the coefficient of x by 2

8/2 = 4. Now find the square of 4 = 4² = 16

Add 16 to both sides of the equation

x² + 8x + 16 = 3  + 16

x² + 2* x * 4 + 4² = 19

{Compare with a² + 2ab + b² = (a + b)² }

(x + 4)² = 19

Both sides take square root,

[tex]\sqrt{(x+ 4)^{2}}=\sqrt{19}\\\\x + 4 = \sqrt{19}[/tex]

x + 4 = ± 4.36

x + 4 = 4.36   ; x +  4 = -4.36

x = 4.36 -4     ;    x  = -4.36 - 4

x = 0.36         ; x = - 8.36

Answer:

11

Step-by-step explanation:

A=8x+8

B=8x-4

A+B=180 degrees

therefore,

8x+8+8x-4=180

16x+4=180

16x=176

x=176/16=11

Step-by-step explanation:

1.5x + 6-3= 4.5x- 2

1.5x+3=4.5x-2

we transposed

4.5x-1.5x= 3+2

3x= 5

we divide both sides by 3

3x/3= 5/3

x= 5/3

The answer is multiply both sides of the equation by 12. Therefore, y/3 × 12=4y while 1/4 × 12=3, then 5×12=60. 4y-3=60.

The answer is multiply both sides of the equation by 12. Therefore, y/3 × 12=4y while 1/4 × 12=3, then 5×12=60. 4y-3=60.Please Mark BRAINLIEST!!! Please

Answer:

multiplied both sides of the equation by 12

Step-by-step explanation:

If he used 3 gallons of gas. Then the amount of the gas in the tank after driving for 2 hours will be 9 gallons.

Algebra is the study of mathematical symbols, and the rule is the manipulation of those symbols.

Mason is driving on a long road trip. He currently has 12 gallons of gas in his car. Each hour that he drives, his car uses up 1.5 gallons of gas.

Then the amount of the gas in the tank after driving for 2 hours will be

The amount of gas used in 2 hours will be

Used gas = 2 x 1.5

Used gas = 3 gallons of gas

Then the remaining amount will be

Remaining amount of gas = 12 - 3

Remaining amount of gas = 9 gallons

what? Ahhahahha

Answer:

62.5%

Step-by-step explanation:

Answer:

The answer is 6.

Step-by-step explanation:

If you divide 2 by 2 you get one so if you divide 12 by 2 you get 6 so the value of h is 6

Answer:

h=6 feet

Step-by-step explanation:

since the smaller figure is a ratio of 1:h and the larger one is 2:12, we can assume that the scale factor (the amount we're multiplying the sides on the smaller figure by to reach the size of the larger figure) is 2. (since 2/1 =2 and 12/2 = 6) :)

Step-by-step explanation:

Answer:

x = 1/5

Step-by-step explanation:

2x − 4 + 2x = −6x −2

Combine the like terms (2x)

Result:

4  −  4  =  − 6  − 2

Add 4 to both sides:

4 −  4 + 4  = − 6 −  2 + 4

Result:

4 = − 6 + 2

Add 6x to both sides.

4  +  6  = − 6  +  2  +  6

Result:

1 0 = 2

Divide both sides by 10:

1 0 / 1 0 = 2/ 1 0

Result:

x = 1/5

Therefore, x = 1/5 would be your answer.
