Question

Factoring Trinomial

Answer 1

A fence will be built around a garden with an area of (49x2 + 56x + 16) ft2. The dimensions of the garden are cx + d, where c and d are whole numbers. Find an expression for the perimeter of the garden. Find the perimeter when x = 5 feet

Answer 2

@Kainui @kidrah69 @Astrophysics @sweetburger @NvidiaIntely little help

Answer 3

\[49x^2+56x+16=(7x)^2+2*7x*4+(4)^2=(7x+4)^2\]
it is a square garden with each edge =7x+4
Perimeter =4(7x+4)=28x+16
put x=5 and find the perimeter

Answer 4

Determine whether each trinomial is a perfect square. If so factor. If not, explain.

Answer 5

@sshayer

Answer 6

it is a perfect square as i have shown
\[49x^2+56x+16=49x^2+28x+28x+16=7x(7x+4)+4(7x+4)=(7x+4)(7x+4)\]

Answer 7

missing part =(7x+4)(7x+4)
