Using the Pythagorean theorem, the diagonal measure is found as
√((18 m)² +(24 m)²) = √(324 +576) m = √900 m
= 30 m

You would be swimming 30 meters.

Carter divided the polynomial 6x2 + 4x + 3 by the monomial 2x using long division, and got an answer of 3x + 2 + . His work is s

Gnesinka [82]

Answer:

C. Both Carter and Demi are correct and would get the same answer.

Step-by-step explanation:

Here, the given polynomial is : $P(x) =6x^2 + 4x + 3$

The given monomial : $Q(x) = 2 x$

Now, according to the given question:

Dividend = P(x), Divisor = Q(x)

Now, Carter divide P(x) by Q (x) with LONG DIVISION METHOD.

If we divide P(x) by Q(x) by Long division, we get:

$\frac{P(x)}{Q(x)} = \frac{(6x^2 + 4x + 3)}{(2x)} = 3x + 2 + \frac{3}{2} x = R(x)$

Also, if Demi divides each term of P(x) by The given monomial (2x) , we get:

$\frac{P(x)}{Q(x)} = \frac{(6x^2 + 4x + 3)}{(2x)} = \frac{6x^2}{2x} + \frac{4x}{2x} +\frac{3}{2x} \\= 3x + 2 + \frac{3}{2} = R(x)$

⇒In both the case, R(X)Quotient is SAME.

Hence, Both Carter and Demi are correct and would get the same answer.

Solve -3x=2x^2-4 using quadratic formula

frozen [14]

Answer:

$x=-2.35078, 0.850781$

General Formulas and Concepts:

<u>Pre-Algebra</u>

Order of Operations: BPEMDAS

<u>Algebra I</u>

Standard Form: ax² + bx + c = 0
Quadratic Formula: $x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}$

Step-by-step explanation:

<u>Step 1: Define equation</u>

-3x = 2x² - 4

<u>Step 2: Rewrite into Standard Form</u>

0 = 2x² + 3x - 4

<u>Step 3: Define variables</u>

a = 2

b = 3

c = -4

<u>Step 4: Find </u><em><u>x</u></em>

Substitute: $x=\frac{-3\pm\sqrt{3^2-4(2)(-4)} }{2(2)}$
Evaluate: $x=\frac{-3\pm\sqrt{9-4(2)(-4)} }{2(2)}$
Multiply: $x=\frac{-3\pm\sqrt{9+32} }{4}$
Add: $x=\frac{-3\pm\sqrt{41} }{4}$
Evaluate: $x=\frac{-3\pm6.40312}{4}$
Evaluate: $x=-2.35078, 0.850781$

And we have our final answer!
