PLEASE HELP!!! <br> Solve the quadratic equation by completing the square.

kow [346]

The values of x in the quadratic equation using completing the square method are $x=-4 \pm \sqrt{5}$ .

Given information:

The quadratic equation is $x^2+8x+11=0$ .

It is required to factorize the given quadratic equation using completing the square method.

<h3>How to factorize a quadratic equation?</h3>

Use completing the square method to solve the equation as,

$x^2+8x+11=0\\(x)^2+2(x)(4)+4^2-4^2+11=0\\( (x)^2+2(x)(4)+4^2)-4^2+11=0\\(x+4)^2-16+11=0\\(x+4)^2=5\\(x+4)=\pm \sqrt{5} \\x=-4 \pm \sqrt{5}$

Therefore, the values of x in the quadratic equation using completing the square method are $x=-4 \pm \sqrt{5}$ .

Find the simple interest earned for principal of $2,000 at and 8% rate for 5 years.

Schach [20]

Answer:

$2800.00

Step-by-step explanation:

A total accrued amount 800 = principal (P) $2000 + interest (I)

R Rate of interest per year decimal - 0.08

X Rate of interest per year percentage - 8%

T time period months or years - 5 years

Equation will be A = P (1 + RT)

first convert X to R = percentage to decimal

X = R/100 = 8%/100 = 0.08 per year

Solving:

A = 2000 (1 + (0.08 x 5)) = 2800

A = $2800

Solve for x -6 >_ 10 - 4x

Otrada [13]

We are given this inequality,

$-6\geq10-4x$

We will follow these steps to solve it:

Step 1:

First let us bring 10 to the left side.

10 is in addition on right, so we apply opposite operation of addition that is subtracting 10 from left side, we get

$-6-10\geq-4x$

$-16\geq-4x$

Step 2:

Next we have to eliminate -4 which is in multiplication with x on the right side.

So applying opposite operation of multiplication that is dividing both sides by -4.

We have to consider here that when we divide or multiply with a negative the sign of inequality reverses, that is ≥ becomes ≤ and vice versa.

$\frac{-16}{-4}\leq x$

x≥4

Answer is last option x≥4.
