X= 1.

For this expression to be correct, you would have to make sure that -4 stays -4. Any negative number subtracted by a positive number makes it go farther down into the negatives as a result even if the 9 is positive.

Hope this helps and have a nice day.

Answer and Step-by-step explanation:

The length of the rectangle is 3 + w (w represents the width).

The polynomial representing the area of the rectangle:

a (area) = w(3 + w) = w^2 + 3w

a = 1

b = 2

c = 3

d = 1

w = 4

(4)^2 + 3(4) = 8 + 12 = 20

e = 20

Answer:

4√2 or 5.66 to the nearest hundredth.

Step-by-step explanation:

Applying the Pythagoras Theorem:_

c^2 = a^2 + b^2

c^2 = 4^2 + 4^2

c^2 = 32

c = √32

c = 4√2

Use polynomial long division to rewrite the following fraction in the form q(x)+r(x)d(x), where d(x) is the denominator of the o

SOVA2 [1]

Step-by-step explanation:

p(x) = 2x^2+8x-12

d(x) = x + 1

r(x) = -13

q(x) = 2x + 6

$\\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 2x +6 \\ x + 1 \sqrt{ {2x}^{2} + 8x - 12} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: {2x}^{2} + 2x \\ \: \: \: \: \: \: \: \: \: \: \: \frac{ \: - \: \: \: \: \: \: - \: \: \: \: \: }{} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 6x - 12 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: 6x + 1 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \frac{ - \: \: - \: \: \: \: \: }{} \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: - 13$

q(x)+r(x)d(x)

= 2x + 6 + (-13) * x + 1

= 2x + 6 -13 * x + 1

= 2x + 6 - 13x + 1

= (- 11x + 7)
