Mathematics

Step-by-step explanation:

Pythagoras (for right-angled triangles) :

c² = a² + b²

c being the Hypotenuse, the side opposite of the right angle. and that would be here the diagonal.

c = diagonal = 10 ft

therefore, the width of the rectangle is 10/2 = 5 ft

10² = 5² + b²

100 = 25 + b²

b² = 75

b = length = sqrt(75) = 8.660254038... ft

a car travels an average speed of 64 miles per hour. how many miles does it travel in 5 hours and 15 minutes?
Contact [7]
Distance is speed or velocity multiplied by time: d = v * t

We know the speed of the car and the time it travelled, so input the two into the equation above and solve for the distance travelled.

d = v * t

d = 64 m/h * (5 hours and 15 minutes) = 64 m/h * (5.25 hours)

d = (64 * 5.25) miles


d = 336 miles

Prove that (n+5)^2-(n+3)^2 is a multiple of 4 for all positive integer values of n
hodyreva [135]

Answer:

Proved

Step-by-step explanation:

Given

(n+5)^2-(n+3)^2

Required

Show that (n+5)^2-(n+3)^2 is a multiple of 4

Expand each bracket

(n+5)(n+5)-(n+3)(n+3)

Open brackets

n^2 + 5x + 5x + 25 - (n^2 + 3x + 3x + 9)

n^2 + 10x + 25 - (n^2 + 6x + 9)

Open bracket

n^2 + 10x + 25 - n^2 - 6x - 9

Collect Like Terms

- n^2 + n^2 - 6n + 10n + 25  - 9

- 6n + 10n + 25  - 9

4n + 25  - 9

4n + 16

Factorize

4(n + 4)

Hence, the multiples of (n+5)^2-(n+3)^2 are 4 and (n + 4)
