What are factors of -40?
(-20)(2)
(-10)(4) (sum of these factors is 6, which is not what we wanted)
(-5)(8) = -40 and the sum of the factors (-5) and (8) is 3.
{-5, 8} is the list of factors of -40 that add up to 3.
That means 1.6 times 10^12
she got that because her number was too big for her screen
1.6 times 10^12=
1,600,000,000,000
I t hink that is 1.6 quadrillion
Answer:
The formula for circumference is: C = 2πr or C = πd
Step-by-step explanation:
C = 2πr
(Circumference equals two times pi times radius)
C = πd
(Circumference equals pi times diameter)
Circumference is the distance around a circle.
Diameter is the measure of one side of the circle to the other.
Radius is half of the diameter.
