: 11 = 1 /3 : 6<br><br> plz help

GenaCL600 [577]

<h3>Let the number be x</h3>

$x:11 = \frac{1}{3} :6$

Divide the numbers

$\frac{x}{11} = \frac{ \frac{1}{3} }{6} \\ \frac{x}{11} = \frac{1}{18}$

Multiply all terms by the same value to eliminate fraction denominators

$11 \times \frac{x}{11} = 11 \times \frac{1}{18}$

Cancel multiplied terms that are in the denominator

$x = 11 \times \frac{1}{18}$

Multiply the numbers

$x = \frac{11}{18}$

The factorization below is missing two positive integers a and b. 6x^(3)+18x^(2)-240x=6x(x-a)(x+b) Factor the polynomial and the

Dvinal [7]

Answer:

a = 5

Step-by-step explanation:

Hello, please consider the following.

$6x^3+18x^2-240x=6x(x^2+3x-40)\\\\\text{** The sum of the zeroes is -3=-8+5 and the product is -40=-8*5. **}\\\\\text{** So, we can factorise. **}\\\\6x^3+18x^2-240x=6x(x^2+3x-40)=6x(x^2+8x-5x-40)\\\\=6x(x(x+8)-5(x+8))\\\\\large \boxed{=6x(x+8)(x-5)}$

So, a = 5.

Thank you.

Part A: If (7^2)^x=1, what is the value of x?<br> Part B: If (7^0)^x=1, what is the value of x?

Fantom [35]

A.
(7^2)^x = 1
(49)^x = 1
thus x = 0

B.
<span>(7^0)^x=1
(1)^x = 1
thus x can be any real number.
