Which statement is correct?
1 answer:
Well... the two rectangles are in the picture below, those are their coordinates
so, you can pretty much see how long one side is, since you can simply count the units on the grid
running a tests on them.... hmmm they'd be similar is the length of the corresponding sides on each figure, give the same ratio

Answer:
Step-by-step explanation:
We'll call the 2 numbers x and y. Starting with the last part of that first sentence "one number is 10 times the other number" can be written, in algebraic form:
y = 10x
Now on to the first statement about the numbers: "twice their sum" is 2(x + y) and "equals their product" is = xy. Putting that all together:
2(x + y) = xy and we know that y = 10x so
2(x + 10x) = x(10x) and
and
and
x(10x - 22) = 0 so
x = 0 or 10x - 22 = 0 which makes
x equal to
So x = 2.2 and y = 22.
