4 0

Hey, I am able to help you today :)

Step 1 - Simplify:
420x^2 - 18 = 2082

Step 2 - Add 18 to both sides:
420x^2 = 2082 + 18

Step 3 - Simplify 2082 + 18 to 2100:
420x^2 = 2100

Step 4 - Divide both sides by 420:
x^2 = 2100/420

Step 5 - Simplify 2100/420 to 5
x^2 = 5

Step 6 - Simplify:
x = 5

Step 7 - Check your answer:
10 x 42 x 5 - 18 =2082

Hope this helps you today :)

Which example has the least percent error?

jeyben [28]

Sample 1:
Error = 14 - 13.7 = 0.3
Percentage Error = 0.3/13.7 x 100 = 2.19%

Sample 2:
Error = 24.4 - 24 = 0.4
Percentage Error = 0.4/24.4 x 100 = 1.64%

Sample 3:
Error = 25.8 - 25 = 0.8
Percentage Error = 0.8/25.8 x 100 = 3.1%

Sample 4:
Error = 40.2 - 39 = 1.2
Percentage Error = 1.2/40.2 x 100 = 2.99%

Sample 2 has the least percent error
