The quadratic form is ax^2 + bx + c
The given equation is 6x^2 -30 = 0
a = 6 because it is with x^2.
There is no x term in the equation so b is 0
c is the numerical term with no variable so c = -30
a = 6
b = 0
c =-30
Answer:
135
Step-by-step explanation:
I am not sure if you have to use the substitution method but I just did (600 - 60) then divided by 4
ANSWER

EXPLANATION
The given rectangle has area,

It was given to us that, the length of the rectangle is l=(x+8)
To find the width, we need to factor, the expression for the area.
We split the middle term to get,

We now factor by grouping;


We know that area of a rectangle is

Hence the width of the rectangle is,
Answer:
C.. is the answer.........
a = length of one side.
Area of a square = a^2
in our problem,
Area = 169 square inches
a = ?
Plug our numbers into the area formula mentioned above.
169 in^2 = a^2.
Take the square root of each side to find the side length of the square shaped platter.
13 = a
