Answer:

Step-by-step explanation:

If x = 6, then the equation can be simplified to 6^2 - 2 (x+5).

If you continue simplifying, you'd get 36 - 2 (6 + 5), then 36 - 22, which equals 14.

Answer:

Step-by-step explanation:

x^2-2(x+5)

Let x=6

6^2 -2(6+5)

We follow PEMDAS, parenthesis first

6^2 -2(11)

Then exponents

36 -2(11)

Then multiply and divide

there are multiple chickens and rabbits in a cage. There are 72 heads and 200 feet inside the cage. How many chickens are in the

mezya [45]

44 chicken and 28 rabbits

Given:
chicken head + rabbit head = 72 heads
chicken feet + rabbit feet = 200 feet

c + r = 72
2c + 4r = 200

find the value of c using the 1st equation:
c = 72 - r

substitute c by its value in the 2nd equation:
2c + 4r = 200
2(72-r) + 4r = 200
144 - 2r + 4r = 200
2r = 200 - 144
2r = 56
r = 56/2
r = 28

c = 72 - r
c = 72 - 28
c = 44

c = 44 ; r = 28

To check:
2c + 4r = 200
2(44) + 4(28) = 200
88 + 112 = 200
200 = 200
