Answer:

See answer below

Step-by-step explanation:

2b(2ab)² - a(2b²)² = XaY³(z - b)

$2b(2ab)(2ab) - a(2b^2)(2b^2) = XaY^3(z-b)$

$8a^2b^3 - 4ab^4 = XaY^3(z - b)$

$4ab^3(2a-b) = XaY^3(z - b)$

X = 4

y = b

z = 2a

Steve and Elizabeth decide to become partners in a children’s cooking school. They need $80,000 for the franchise. They invest i

PilotLPTM [1.2K]

Answer:

The share of Steve is $34,285 .71

The share of Elizabeth is $45,714.28

Step-by-step explanation:

The total investment of Steve and Elizabeth in cooking school = $80, 000

The ratio of investment of Steve and Elizabeth = 3: 4

Let us assume the common factor in the ratio is m.

So, the ratio of Steve = 3 m

and the ratio of Steve = 4 m

So, according to the question:

⇒ 3 m + 4 m = 80,000

or, 7 m = 80,000

⇒ m = 80,000 / 7 = 11,428.57

or, m = 11,428.57

⇒ The share of Steve = 3 m = 3 x (11,428.57) = 34,285 .71

⇒ The share of Elizabeth = 4 m = 4 x (11,428.57) = 45,714.28

HURRYY!!! Identify the zeros of f(x) = (x − 3)(x + 9)(4x − 3).

tiny-mole [99]

Answer:

The value of x is -9, 3/4 and 3.

Step-by-step explanation:

In order to find the value of x, tou have to let f(x) equals to 0 :

Let f(x) = 0,

(x-3)(x+9)(4x-3) = 0

x - 3 = 0

x = 3

x + 9 = 0

x = -9

4x - 3 = 0

4x = 3

x = 3/4
