So a square is a parallelogram with four sides of equal length and angles of equal size. <span>In other words, all squares are parallelograms, but only some parallelograms are squares.</span>
Answer:
30
Step-by-step explanation:
discounting by 20% is the same as marking to 80% of the original cost. 80% = .8
set up equation and solve
.8x=24
x=30
The first equation is x+x+3x+3x. You know that the perimeter is w+w+l+l, so, you can simply substitute the width, x, and the length, 3x (Three times the width).
The second equation is 8x. This comes from the first expression. If you have three of something plus three of the same thing plus one of the same thing plus one of the same thing, you have 8 of that thing. In other words, combine like terms.
I hope this helped! :) if it didn't, comment please!!!
Answer:
200×100=20000
200×1,000= 200,000
200×0.1= 20
200×0.01= 2
200×0.001= 0.2
Step-by-step explanation:
Point slope form is
y-y1=m(x-x1)
where slope=m
and (x1,y1) is a given point
slope=(y2-y1)/(x2-x1)
slope=(6-7)/(-8-(-5))=-1/(-8+5)=-1/-3=1/3
pick any point
(x,y)
(-5,7)
y-7=1/3(x+5) or
y-6=1/3(x+8)
