Answer:
The ratio of the areas of the smaller rectangle to the larger rectangle is 
Step-by-step explanation:
we know that
if two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z-----> the scale factor
x-----> the area of the smaller rectangle
y----> the area of the larger rectangle
so

substitute the values

simplify

That means, the area of the larger rectangle is 9 times the area of the smaller rectangle
------> the scale factor
That means, the dimensions of the larger rectangle is 3 times the dimensions of the smaller rectangle
Answer:
Step-by-step explanation:
3n + 5p + 2 + n
Add up all the 'n's : 4n + 5p + 2
That's all you can do with it

can also be written as 2i
where i = √-1

Rationalizing denominator,
Answer: x<17.5
Step-by-step explanation:
Subtract from both sides: x+2.5-2.5<20-2.5
Simplify the arithmetic: x<20-2.5
Simplify the arithmetic: x<17.5
Hope it helps!
Answer:
{x | x ≤ -20}
Step-by-step explanation:
x + 17 ≤ -3
Subtract 17 from each side
x + 17-17 ≤ -3-17
x ≤ -20
