A quadrilateral has 4 sides and each side has a different label. Top side is (4 x squared + 8 x) inches. Left side is 31 inches. Right side is (3 x squared minus 5 x + 20) inches. Bottom side is (7 x + 30) inches.
Find the perimeter of the quadrilateral.

If x = 2, the perimeter is
inches

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

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

the answer is 150.6

step-by-step explanation:

you multiply .02 by 30 and get .6.

and then you multiply 5.00 by 30 and get 150.

hope this !
