The perimeter of the rectangle is equal to the doubled sum of the sides, and the area is equal to the product of the sides. So we have the following equation
3 x 2x = 2(3 + 2x)
6x = 6 + 4x
2x = 6
x = 3
It is really easy it is 6
Step-by-step explanation:
(i) From the graph value of x varies -3 to 3 i.e.
and domain in the input values which function can take
So, option (d) is correct.
(ii) option (d) is correct as it represent the function 
. While all the other function does not satisfy the given conditions.
(iii) 
are the parts of solution pair.
(iv) Option (c) and (d) represents the function as each element of the first set has a unique image in the second set.
Answer:
=−3x+42
Step-by-step explanation:
Let's simplify step-by-step.
−4(x−7)+x+14
Distribute:
=(−4)(x)+(−4)(−7)+x+14
=−4x+28+x+14
Combine Like Terms:
=−4x+28+x+14
=(−4x+x)+(28+14)
=−3x+42
First you need to find the middle number, wich is 75. Since there is no $75, I would go with $80.
