Hi there!

~

$( 2x + 3y)^2$

$= (2x + 3y) (2x + 3y)\\= (2x)(2x)+ (2x) (3y) + (3y)(2x) +(3y)(3y)\\=4x^2 + 6xy + 6xy + 9y^2\\= 4x^2 + 12xy + 9y^2$

Answer : $4x^2 + 12xy + 9y^2$

Hope this helped you!

Clara is building a triangular garden. She wants the length of the longest side to be three more than twice as long as the lengt

pantera1 [17]

Alrighty-
So here we go.
Let's first go over any given values.

Shortest side = s

And we know that
3rd side = 12

Now for the longest side
"Three more" means +3
"...twice as long as the shortest side"
Means 2s

Longest side = 3+2s

Now we put this in the correct format:

P = 12 + s + (3+2s)

We can simplify further:
P = 12 + s + 3 + 2s
P = 15 + s + 2s
P = 15 + 3s

ANSWER: P = 12 + s + (3+2s)

SIMPLIFIED: P = 15 + 3s
