Wich runs faster: a cheetah that can run 60 feet in 6 seconds or a gazelle that can run 100 in 10 seconds?

Well, you would have to find both of their average rates of change to find who can run faster. If a cheetah can run 60 feet in 6 seconds, then the cheetah goes 10 feet per second. And if a gazelle can run 100 feet in 10 seconds, that would mean that the gazelle ran 10 feet per second. (You would find this by dividing.)

They both go at the same pace. Neither is faster.

The width of a rectangle is the length minus 7 units. The area of the

AleksandrR [38]

Answer:

8 units

Step-by-step explanation:

here's your solution

=> let the length of rectangle be X

=> then width = x - 7

=> area = 8units

=>> area = length*width

=> area = x (x-7) = 8

=> x^2 - 7 = 8

=> now, x^2 - 7x - 8 = 0

=> factories the above equation by middle term split

=> x^2 - 7x - 8

=> x^2 - 8x + x - 8

=> take the common

=> x(x - 8) + 1(x - 8)

=> (x + 1) (x - 8)

neglect (x + 1) because this will in negative for X

=> x - 8 = 0

=> x = 8

=>so, x = 8

=>length = 8 units

PLZ ANSWER QUICK!!!

alexira [117]

Answer; c^2 = a^2 + b^2

c = 17 inches

a = 8 inches

b^2 = c^2 – a^2

b^2 = 17^2 – 8^2

b^2 = 289 – 64

b^2 = 225

b = square root of 225

b = 15 inches ≈ c.
