Answer: YES

Step-by-step explanation:

<u>THREE WAYS TO DETERMINE: </u>

If the number given is in integer, it is rational.

If the number given is fraction, it is rational.

If the number given is decimal, as long as it is terminating or repetitive decimal, it is rational. (Because then you can write it as a fraction which leads to the second point)

----------------------------------------------------

-5 3/8

It is a fraction, which fits the second point.

<h2>So, it is rational</h2>

Hope this helps!! :)

$width=8+x+x=8+2x\\length=9+x+x=9+2x\\\\Area:A=width\cdot length\\\\A=(8+2x)(9+2x)=(8)(9)+(8)(2x)+(2x)(9)+(2x)(2x)\\\\=72+16x+18x+4x^2=4x^2+34x+72\\\\A=75ft^2\\therefore\\\\4x^2+34x+72=75\ \ \ \ |subtract\ 75\ from\ both\ sides\\\boxed{4x^2+34x-3=0}$

The variables A, B, and C represent polynomials where A = x + 1, B = x2 + 2x − 1, and C = 2x. What is AB + C in simplest form?

topjm [15]

AB + C
= (x + 1)(x^2 + 2x - 1) + 2x
= x^3 + 2x^2 - x + x^2 + 2x - 1 + 2x
= x^3 + 3x^2 + 3x - 1

Answer:

a) x =3 and x=5

c) x =-1 and $x = \frac{-7}{3}$

i) x =0 and $x = \frac{-9}{2}$

Step-by-step explanation:

Given that the quadratic equation

x² - 8x +15 =0

The factors of 15 = 5 × 3

x² - 5x -3x +15 =0

x(x -5) -3(x-5) =0

(x-3)(x-5) =0

x =3 and x=5

3 x² + 10 x +7 =0

⇒ 3x² + 3x + 7x +7 =0

⇒ 3x (x +1) +7(x+1) =0

⇒ (x+1) ( 3 x +7) =0

⇒ x =-1 and $x = \frac{-7}{3}$

2 x ² + 9 x =0

⇒ x( 2 x + 9) =0

⇒ x =0 and 2 x = -9

⇒ x =0 and $x = \frac{-9}{2}$
