The uniforms will cost 1,360, so yes they have enough money to buy 11 uniforms.
Hope this helps.
area of floor = length * width
length =18 feet
width =12 feet
area =12*18 = 216 feet square
Step-by-step explanation:
x²-y²=12
(x-y)(x+y)=12
but x-y=4
4(x+y)=12
x+y=12/4
x+y=3
lets make x the subject of the formula
x=3-y
since x-y=4
(3-y)-y=4
3-y-y=4
-2y=1
y=-1/2
then x=3-y
x=3-(-1/2)
x=(6--1)/2
x=7/2
therefore; x²+2xy+y
=(7/2)²+2×7/2×-1/2+(-1/2)
=49/4-7/2-1/2
=(49-14-2)/4
=33/4
=8.25
=8
B -4-1 because the one is positive and the 4 is negative
