Answer:
3.6 x 10⁵ g of sodium chloride
Step-by-step explanation:
You can see the polygon in the attached figure.
It's a trapezoid, so it's not equilateral, nor regular.
We have an object measured in <u>Meters</u>, and we want to cut sections of it off in <u>Centimeters</u>, a different unit of measurement.
Because we're subtracting sections of the pipe, we want to make the units the same, this will make our calculations easier.
1 Meter = 100 Centimeters, so, <u>2.5 Meters = 250 Centimeters</u>
We're cutting ( 60 Cm + 35 Cm + 90 Cm ) off, which totals <u>185 Cm</u>.
250 Cm Pipe - 185 Cm Cuts = 65 Cm Pipe Left
So the answer is (2c – 3) (2c – 3) or (2c – 3)^2
10 and -7 times each other equals -70.
10 plus -7 equals 3.
Hope this helps you! (:
