Write a quadratic equation in standard form that has 5 3 and 7 3 as its roots. A) 9x2 − 36x + 35 = 0 B) 9x2 + 36x − 35 = 0 C) 9x

Serggg [28]

Answer:

Option A)

$9x^2 - 36x + 35 = 0$

Step-by-step explanation:

We are given the following in the question:

Roots of quadratic equation are:

$\alpha = \dfrac{5}{3}, \beta = \dfrac{7}{3}$

The sum of the roots and the product of the roots can be calculated as:

$\alpha + \beta = \dfrac{5+7}{3} = 4\\\\\alpha\beta = \dfrac{5}{3}\times \dfrac{7}{3} = \dfrac{5}{9}$

Standard form of quadratic equation:

$x^2-(\alpha + \beta)x+\alpha\beta = 0$

Putting values, we get,

$x^2 - 4x + \dfrac{35}{9} = 0\\\\9x^2 - 36x + 35 = 0$

is the required quadratic equation.

Thus, the correct answer is

Option A)

$9x^2 - 36x + 35 = 0$

Ross is shopping for mulch that costs $1.29$1.29 per cubic foot. During his first trip to the store, he bought 16.516.5 cubic fe

stich3 [128]

You add $1.29 and $1.29 and 16.5 and 16.5 and 4.5 and 4.5 and that equals $44.58.

I hope I helped you! :)

$1.29 + $1.29 + 16.5 + 16.5 + 4.5 + 4.5 = $44.58.

What is the simplest form of the radical expression?

BaLLatris [955]

I believe the equation is
$4 \sqrt[4]{2x} + 6 \sqrt[4]{2x}$
In this case, you would simplify it by adding them together.
$4 \sqrt[4]{2x} + 6 \sqrt[4]{2x}$ = $10 \sqrt[4]{2x}$
And can even be changed to an exponential equation:
$10(2x)^{ \frac{1}{4} }$

Which step is incorrect and what is the correct answer?

Anit [1.1K]

Answer:

Step 4, x = 3

Step-by-step explanation:

Step 4 was wrong, instead of 6x = 6, it should be 6x = 18. They shoudl've added 6 to both sides instead of subtracting 6 as ur trying to cancel out the 6 on the left side of the equation. So:

6x = 18

x = 3
