Step one: multiply and divide in order. Step two: add and subtract like terms. Step three: get X alone on one side (what you do to one side you have To do to the other side) Step four: simplify and solve :)

ANSWER

x = - 2 \pm i

EXPLANATION

We use the method of completing the squares.

The equation is
3 {x}^{2} = - 12x - 15

We rewrite the above equation to obtain;

3 {x}^{2} + 12x = - 15

We divide through by 3 to obtain;

{x}^{2} + 4x = - 5

We add half the coefficient of
x

to both sides of the equation to get,

{x}^{2} + 4x + {2}^{2} = - 5 + {2}^{2}

The right hand side is now a perfect square.

{(x + 2)}^{2} = - 1

We now take square root of both sides to get;

x + 2 = \pm \sqrt{ - 1}

We add -2 to both sides,

x = - 2 \pm \sqrt{ - 1}

We simplify to obtain,

x = - 2 \pm i

I would have to say SAS because they give 2 sides and an angle. Also 3:4 because the one side is 3 and add 1 for 4, same for 30 and 40.

The area of the rectangular garden given the length and width is 16 1/2 square feet

<h3> Area of the garden</h3><h3 />
  • Length = 5 1/2 feet
  • Width = 3 feet

Area of a rectangular garden = length × width

= 5 1/2 feet × 3 feet

= 11/2 × 3

= 33/2

= 16 1/2 square feet

A farmer has both pigs and chickens on his farm there are 78 fee and 27 heads how many pigs and how many chickens are there
Andre45 [30]
Assuming health non-mutated animals:
Feet = 4*Pigs + 2*Chickens
Heads = Pigs + Chickens

By back substitution:
78 = 4*(27-Chickens) + 2*Chickens
78 = 108 -2*Chickens
-30 = -2*Chickens
Chickens= 15

Then:
27 = Pigs + 15
Pigs = 12

To check:
Feet = 4*Pigs + 2*Chickens
78 = 4*12 + 2*15
78 = 48 + 30
78 = 78 CHECKS
