Step-by-step explanation:
Area of square = x^2
Area of rectangle = xy
Let x = side of square
Let x + 3 = width of rectangle
Let x + 5 = length of rectangle = y
Here is the set up:
x^2 + (x + 3)(x + 5) = 249
You finish.
Answer:
Linear, the linear term is -21x and the constant term is -20. Last option is the answer
Step-by-step explanation:
We are given the following function:

First we have to simplify y, before solving the question:

Applying the distributive property:



No quadratic term, so it is linear.
The linear term is -21x and the constant term is -20.
3/4n -18= 1/4n -4
⇒ 3/4n -1/4n= -4+18
⇒ 2/4n= 14
⇒ 1/2n= 14
⇒ n= 14/(1/2)
⇒ n= 14* (2/1)
⇒ n= 28
Final answer: n= 28~
