ANSWER
a. d+4
b. 4d+16
EXPLANATION
The area of the square coaster is represented by:

We split the middle term to obtain,

We factor by grouping to get,


Since area of a square is l² , it means the side length of the square is

b) The perimeter of a square is given by

We substitute the length in terms of d, to obtain;

Or

Answer:

Methods to Solve the Quadratic Equations. There are some methods to solve the quadratic equation. They are, 1. Factorization method 2. Completing square method 3. Formula method 4. Graphical Method. Solving Quadratic Equation by Factorization Method
F(4) = -4(4) - 3 = -16 - 3 = -19
answer
f(4) = -19
g(-4) = 2(-4)^2 - 3(-4) = 2(16) + 12 = 32 + 12 = 44
answer
g(-4) = 44
Answer:
Since we know that each of the three triplets are the same age we can put next to n, 3.
And given that another child is 14 years old we can put that next to the "+" sign.
In total, it would equal 32, so put the 32 after the equal sign.
It should look like this:
3n + 14 = 32
But now they want us to solve for the triplet's ages, so we just solve for n;
3n + 14 = 32
-14 -14
3n = 18
/3 /3
n = 6, the triplet's ages are 6 years old each.
