Which equation is quadratic in form?
Drupady [299]

we know that

A quadratic equation is a polynomial with an order of two. Its general form is

ax^{2} + bx + c = 0

case a) 6(x + 2)^{2} + 8x + 2 + 1 = 0

6(x + 2)^{2} + 8x + 2 + 1 = 0 \\ 6(x^{2} +4x+4)+8x+3=0\\ 6x^{2} +24x+24+8x+3=0\\ 6x^{2} +32x+27=0\\\\ a=6\\  b=32\\ c=27

<u>The case a) is a quadratic equation</u>

case b) 6x^{4} + 7x^{2} - 3 = 0

<u>The case b) is a grade 4 polynomial</u>

case c) 5x^{6} + x^{4} + 12 = 0

<u>The case c) is a grade 6 polynomial</u>

case d) x^{9} + x^{3} - 10 = 0

<u>The case d) is a grade 9 polynomial</u>

therefore

the answer is

6(x + 2)^{2} + 8x + 2 + 1 = 0

For this case we must find the quotient of the following expression:

\frac {(- 8x ^ 2 * y) (- 7x ^ 5 * y ^ 3)} {- 2x ^ 2 * y ^ 3}

We can rewrite the expression as:

(We take into account that- * - = +)

\frac {56x ^ 2 * y * x ^ 5 * y ^ 3} {- 2x ^ 2 * y ^ 3} =

By definition of multiplication of powers of the same base, we place the same base and add the exponents:

\frac {56x ^ {2 + 5} * y ^ {1 + 3}} {- 2x ^ 2 * y ^ 3} =\\\frac {56x ^ {7} * y ^ {4}} {- 2x ^ 2 * y ^ 3} =

By definition of division of powers of the same base, we place the same base and subtract the exponents:

-28x^{ 7-2} * y^{ 4-3} =\\-28x ^ 5 * y

Answer:

-28x ^ 5 * y

The cost for groceries was $11.20 before sales tax. How much was the total cost of groceries after the 5% sales tax was charged?
AveGali [126]
To convert a percentage to a decimal we divide it by 100. So, 5% = .05

To find the tax, multiply the cost by the tax rate

(.05)(11.20) = 0.56

Add this to the cost to get the total

$11.20 + $0.56 = $11.76
