|a| − |b| +| c| , if a=−8; b=−5; c=1

4

Step-by-step explanation:

|a| − |b| +| c|

Let a=−8; b=−5; c=1

|-8| − |-5| +| 1|

The absolute value means take the positive value

2πrh+2πr²

2 (pie)(radius)(height)+2(pie)(radius)^2

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
