Suppose a, b, c, and d are different positive integers whose sum is 100, and a-c=5. what is the greatest possible value of ab-cd?

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

8.3 and the 3 is repeating

hope this .

isosceles for b.

step-by-step explanation:

if two sides of a triangle are equal, it is called an isosceles triangle.
