Answer:
x^2+2xy+y^2
Step-by-step explanation:
(x + y)(x + y)
FOIL
first x*x = x^2
Outer x*y = xy
inner: y*x = xy
last y*y = y^2
add together
x^2+xy+xy+y^2
Combine like terms
x^2+2xy+y^2
Using a system of equations, it is found that the total amount of money the two ladies spent was of $782.
<h3>What is a system of equations?</h3>
A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
In this problem, the variables are:
- Variable x: Amount Mrs. Smith had initially.
- Variable y: Amount Mrs. Wilson had initially.
Mrs smith had $46 more than Mr.s Wilson at first, hence:
x = y + 46.
Mrs Wilson spent 4/7 of her money on some clothes and, and Mrs. Smith spent 3/5 of her on household items, then they remained with an equal amount, so:
Since x = y + 46, we have that:
14(y + 46) = 15y
y = 14 x 46
y = $644
x = 644 + 46 = $690
Hence the amount they spent is given as follows:

Answer:
Step-by-step explanation:
Midpoint of line segment = (1,-3)
Slope of line segment = (-1-(-5))/(3-(-1)) = -3/2
Perpendicular bisector:
y+3 = ⅔(x-1)
y = ⅔x - 11/9
