Call the number to be squared = x
Then the expression is x^2 - 6
If there is more to the question, please put it in a comment and I'll edit this.
<span>Chicken have 2 legs. Rabbits have 4 legs. Let the number of chicken be x and the number of rabbits be y. Then we have the following equations: x + y = 72 (the total number of animals in the cage) and 2x + 4y = 200 (the total number of legs in the cage). In the first equation we express x relative to y and get that x = 72 - y. Then we replace it in the second equation and get 2*(72 - y) + 4y = 200 <=> 144 + 2y = 200 <=> y = 56/2 <=> y = 28. And since x = 72 - y we get that x = 44. So in total we have 44 chicken and 28 rabbits.</span>
Answer:
-17
Step-by-step explanation:
-3-14 = -17
-17 + 14 = -3
If x varies directly with y, then :
● Increase in x results in increase of y
● Decrease in x results in decrease of y
● It is represented by : x ∝ y
Here : x₁ = 6 and y₁ = 15 and x₂ = x₂ and y₂ = 20
Substituting the values we get :
<u>Answer</u> : x = 8 when y = 20
The answer is B) 8 points out of 14 because A) has a 10 point difference, B) has a 6 point difference, C) has a 20 point difference and D) has a 75 point difference. so B) is the answer.
hope that helps:)
