Mathematics

Tanzania [10]3 years ago

Answer:

(x+3)m

Step-by-step explanation:

Area of a rectangle = Length × width

Given the area = (x²-9)m²

Width = (x-3)m

Length of the rectangle = Area/Width

Length of the rectangle = x²-9/x-3

= x²-3²/x-3

Note that according to different of two square, a²-b² = (a+b)(a-b)

Therefore x²-3² = (x+3)(x-3)

Length of the rectangle

= (x+3)(x-3)/x-3

= x+3

The length of the rectangle is (x+3)m

Vedmedyk [2.9K]

Answer:

The experimental probability of the coin landing tails-side up is <u>60</u><u>%</u><u>.</u>

10/10 - 4/10= 6/10 now convert 6/10 into a percentage, 60/100=<u>60%</u>
