Hector has a rectangular garden that measures 13 m wide by 15 m long. He wants to increase the area to 255 m2 by increasing the width and length by the same amount. What will be the length (longer dimension) of the new garden?

Answers

Answer 1

Answer: let x be the length loner
(15+x)*(13+x)=255
x^2+28x+195=255
x^2+28x-60=0
( x-2)(x+30)=0
x=2 or x=-30 (rejected)
Therefore the length longer is 2 m

you bring the decimal point 2 places to the right.

answer is A

We want to write the decimal number 0.035 in percent form. So, to convert this value to percent, we just multiply it by 100.
In this example multiplying 0.035 by 100, we get 3.5 (the value in percent).

Step 1: Move the decimal point two places to the right: 0.035 → 0.35 → 3.5.
Step 2: Add a % sign: 3.5%So, 0.035 is equivalent to 3.5% in percent form.
