Answer:

$\frac{3x}{x + 2} + \frac{4x}{x - 2} \\ \frac{(3x(x - 2) + (4x(x + 2))}{(x + 2)(x - 2)}$

(3x²-6x+4x²+8x)/(x²-2²)

(7x²+2x)/(x²-4)

comparing with

ax²+bx/x²+c

we get

a=7

b=2

c=-4

Item 2

Inessa05 [86]

The question is an illustration of a division model.

The boxes will be completed with: 1650, 231, 50 and 7

The expression is represented as:

$\mathbf{1881 \div 33}$

Express 1881 as 1650 + 231.

$\mathbf{1881 \div 33 = (1650 + 231) \div 33}$

Split

$\mathbf{1881 \div 33 = 1650 \div 33 + 231 \div 33}$

Evaluate each division

$\mathbf{1881 \div 33 = 50 + 7}$

$\mathbf{1881 \div 33 = 57}$

The above illustration means that, the boxes will be completed with the following numbers

1650
231
50
7

See attachment for proper illustration

Which statement BEST describes the growth of bacteria modeled by the function f(x)=1.8x

lara [203]

Answer:

Step-by-step explanation:

f(x) = 1.8x is a linear function and does not model the growth of bacteria. Perhaps you meant f(x) = 1.8^x, which is an exponential function whose initial value is 1. Please ensure that you have copied down this problem exactly as it was presented.
