Answer:
x = sqrt(5)
Step-by-step explanation:
The ratio of the areas is equal to the ratio of the side lengths squared
20 5^2
----- = -----
4 x^2
Using cross products
20 x^2 = 4 * 5^2
20x^2 = 4*25
20x^2 = 100
Divide by 20
20x^2 = 100/20
x^2 = 5
Take the square root of each side
sqrt(x^2) = sqrt(5)
x = sqrt(5)
1 cm = 20 km
so 3.5 cm would equal : 3.5 * 20 = 70 km <==
Answer:
y=4, x=-5

Well, we could merge the two equations together to do as shows:
4(2y-13)-3y=-32
8y-52-3y=-32
5y-52=-32
5y=20
y=4
To find x, we'd do
4x-3(4)=-32
4x-12=-32
4x=-20
x=-5
