The product of two consecutive integers is 56.find the the integers.
defon

Let, the integers = x,(x+1)

x*(x+1) = 56

x²+x = 56

x²+x-56 = 0

x²+8x-7x-56=0

x(x+8)-7(x+8)=0

x+8= 0  OR x-7=0

x = -8 OR x = 7

it would be -8 & -7 or 7 & 8

The diameter of the circle is 9.7 m . Calculate the length of its circumference. Round to the nearest tenth and remember to use
RSB [31]

Answer:

30.4m

Step-by-step explanation:

Diameter(D) = 2r (radius)

D = 9.7m

r = 9.7m / 2

= 4.85m

C = 2πr

= 2π × 4.85m

= 30.47344873982099m

rounding - Leave it as is if the digit in the tenth is 4 or lower

- round it up if it's 5 or higher.

~~ 30.4m
