{x}^{2}   + 4x - 12 = 0 \\  {x}^{2}  + 4x + 4 - 4 - 12  = 0\\   {(x + 2)}^{2}  - 16 = 0 \\ x =   -   +  \sqrt{16}  - 2 \\ x =   + \:  or - 4 - 2 \\ x =  - 6 \:  \: x = 2
- subtract the 12 from both sides so that it becomes the last constant term in the quadratic equation which should now equal 0.
- take the 4x
- half the coefficient of 4 (2)
- square it (4)
- add it to the equation (+4)
- subtract it from the equation (-4)
- factorise the square (x+2)^2 expands to (x^2 + 4x + 2) as {a+b}^2={a^2 + ab + ba + b^2}
- now the equation is in turning point form.
- to find x, add 16 and square root 16 and (x+2)
- subtract 2 from positive or negative 4 (as -4^2 and 4^2 both equal 16).
- This should give you two values for x, -6 and 2.


I really hope that this helped :)

You have one type of candy that sells for $1.70/lb and another type of candy that sells for $3.40/lb. You would like to have 8.5
Andrew [12]

Answer: You will need 3.5lbs of the cheaper candy

and 5 lbs of the expensive candy.

Step-by-step explanation:

Let x represent the number of pounds of the cheaper candy that you would need.

Let y represent the number of pounds of the expensive candy that you would need.

You would like to have 8.5 lbs of a candy mixture. It means that

x + y = 8.5

You have one type of candy that sells for $1.70/lb and another type of candy that sells for $3.40/lb. The candy mixture would sell for $2.70/lb. It means that the total cost of the mixture would be 8.5 × 2.7 = $22.95. The expression would be

1.7x + 3.4y = 22.95- - - - - - - - - - - 1

Substituting x = 8.5 - y into equation 1, it becomes

1.7(8.5 - y) + 3.4y = 22.95

14.45 - 1.7y + 3.4y = 22.95

- 1.7y + 3.4y = 22.95 - 14.45

1.7y = 8.5

y = 8.5/1.7

y = 5

x = 8.5 - y = 8.5 - 5

x = 3.5

Find the measure of angle 3=
andre [41]

Answer: <em>50°</em>

Step-by-step explanation:

<em>Since angle 3 is in a right triangle we can assume one angle is 90°</em><em> </em><em>and then the other missing angle will be 40°</em>

<em>Because you take 180°-140°(the angle next to it) which will equal 40°</em>

<em>Now every triangle must add up to 180°</em>

<em>so lets take the angles we have now</em>

<em>90° +40°=130°</em>

<em>now take that 130°</em>

<em>180°-130°=</em><em>50°</em>

<em>Now check your work</em>

90°+40°+50°=180°

Angle 3 is 50°
