Answer:

21 pieces of chickens.

Step-by-step explanation:

Given:

The farmer has a total of 40 animals. ( cows and chicken )

He counts the legs of all his animals and realizes he has a total of 118 legs.

Question asked:

How many chickens does the farmer have ?

Solution:

Let number of chickens = $x$

Then number of cows = $40-x$

Now, as here given that total number of legs are 118 of all the animals, and as we know that a chicken has two legs and cow has four legs, hence the equation will be :

Total number of legs = Number of legs having chickens + Number of legs having cows

$118 = 2x+4(40-x)\\118=2x+160-4x$

$118=-2x+160$

Subtracting both sides by 160

$-42=-2x$

By adding both sides by minus

$42 = 2x\\$

By dividing both sides by 2

$x =21$

Hence, farmer have 21 pieces of chickens.

Step-by-step explanation:

(X1,Y1) = (-2,2)

(X2,Y2) = (0,1)

• Find slope.

m = (Y2 - Y1)/(X2 - X1)

m = (1 - 2)/(0 - (-2))

m = -1/2

The answer is C.

Question 21

horsena [70]

Answer:

A(x) = 6x² + 26x

Step-by-step explanation:

A(x) = 4x ( x + 10 ) - 2x ( 8 ) + $\frac{2x(x)}{2}$ + $\frac{2x(x+2)}{2}$

A(x) = 4x² + x² + x² + 40x - 16x + 2x

A(x) = 6x² + 26x
