ANSWER
C
E
F
EXPLANATION
The result of the synthetic division is :
3 -1 0
The last number is the remainder which is 0
The first two numbers are the coefficients of the quotient.
Therefore the quotient is 3x -1
Since the remainder is 0, x-4 is a factor of
This also means that:
This again means that x=4 is a root of
The correct choices are C,E and F.
Let the side of the garden alone (without walkway) be x.
Then the area of the garden alone is x^2.
The walkway is made up as follows:
1) four rectangles of width 2 feet and length x, and
2) four squares, each of area 2^2 square feet.
The total walkway area is thus x^2 + 4(2^2) + 4(x*2).
We want to find the dimensions of the garden. To do this, we need to find the value of x.
Let's sum up the garden dimensions and the walkway dimensions:
x^2 + 4(2^2) + 4(x*2) = 196 sq ft
x^2 + 16 + 8x = 196 sq ft
x^2 + 8x - 180 = 0
(x-10(x+18) = 0
x=10 or x=-18. We must discard x=-18, since the side length can't be negative. We are left with x = 10 feet.
The garden dimensions are (10 feet)^2, or 100 square feet.
