The area of miguels rectangular garden is 450 square feet. The garden is 9 feet wide. How many feet of fencing will Miguel need
sattari [20]

Answer: 118 feet

Step-by-step explanation:

For a rectangular shape: Area = W × L

450 = 9 × L

450 ÷ 9

L = 50

Perimeter of a rectangular shape = 2L + 2W

Perimeter = (2 × 50) + (2 × 9)

= 100 + 18 = 118 feet

Please someone help me, I will give you brainliest <br><br> Factor the expression: y^2 + y + 1/4
Firdavs [7]

Answer:

y² + y + \frac{1}{4} = (y + \frac{1}{2})²

Step-by-step explanation:

In most cases, we can factor a polynomial, or quadratic, by looking at the factors of the last term.  In this case, the last term is \frac{1}{4}.  When we factor a polynomial, we are looking for two expressions that when multiplied together using FOIL (forward-outside-inside-last) will give us the polynomial.  For example: (a + b)(a + b) or (a+ b)².

In order to get y² + y + \frac{1}{4}, we are looking for a 'c' value that will add up to '1' which is our 'b' value (ay² + by + c).

Since \frac{1}{2}*\frac{1}{2}=\frac{1}{4}and\frac{1}{2}+\frac{1}{2}=1

Then, we can use \frac{1}{2} as our factor for both expressions.  Putting this together we get:  (y + \frac{1}{2})(y + \frac{1}{2}) or (y + \frac{1}{2})²

Two of the steps in the derivation of the quadratic formula are shown below.
Svetllana [295]

The step 7 is a wrong step, because in the denominator 1 is written in place of 2.

<h3>What is a quadratic equation?</h3>

The quadratic equation is given as ax² + bx + c = 0. Then the degree of the equation will be 2. Then we have

Two of the steps in the derivation of the quadratic formula are shown below.

The equation is given below.

\rm \dfrac{b^2 - 4ac}{4a^2} = \left (x + \dfrac{b}{2a} \right )^2

Then the above equation can be written as

\rm \pm \sqrt{ \dfrac{b^2 - 4ac}{4a^2}} = \left (x + \dfrac{b}{2a} \right )\\\\\\x = \dfrac{-b}{2a} \pm \sqrt{ \dfrac{b^2 - 4ac}{4a^2}}\\\\\\x = \dfrac{-b}{2a} \pm \dfrac{\sqrt{ b^2 - 4ac}}{2a}\\\\\\x = \dfrac{-b \pm \sqrt{ b^2 - 4ac}}{2a}

The step 7 is a wrong step, because in the denominator 1 is written in place of 2.

More about the quadratic equation link is given below.
