Ineed on this

round and estimate only 74(711
and 22(890

i've been stuck on this for 4 hours i cant learn well

for how many digits is rounding required to occur?

if it's one digit, it should be 70,000 and 20,000

if it's two digits it would be 75,000 and 23,000

if it's three digits it would be 74,700 and 22,900

if it's four digits it would be 74,710 and 22,980

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
