5 * 12 = 60 (for the whole area)
3 * 2 = 6 (for the missing space)
6 + 2 = 8
12 - 8 = 4
4 * 3 = 12
12 / 2 = 6
6 + 6 = 12
60 - 12 = 48
Answer: 48

A map of a highway has a scale of 2 inches = 39 miles. The length of the highway on the map is 9 inches. There are 7 rest stops
Jlenok [28]

Scale : 2 inches = 39 miles

The length of the highway on the map is 9 inches -> the real length of it = 39 x 9 : 2 = 175.5 (miles)

There are 7 rest stops equally spaced => There are 7-1 = 6 equal distance between the rest stops

So, every rest stop is 175.5 : 6 = 29.25 miles apart from each other.

With a scale of 1 inch = 30 miles, each rest stop will be 29.25 : 30 = 0.975 inches apart from each other on the new map.

If ab = 9 and a² + b² = 81, then (a+b)² = ?​
Andre45 [30]

Answer:

99

Step-by-step explanation:

Through some clever algebra, we can combine our first two equations using the fact that

(a+b)^2=a^2+2ab+b^2

We have the a² and the b² in the equation a^2+b^2=81, and we <em>almost </em>have a 2ab in the equation ab=9. To get that 2ab, we can simply double both sides of the first equation to get 2ab=18. From there, we'll add the first two equations together, giving us the summed equation

a^2+b^2+2ab=81+18\\a^2+2ab+b^2=99

And since (a+b)^2=a^2+2ab+b^2, we can equivalently say that

(a+b)^2=99
