A youth soccer field is a rectangle 110 yards long and 60 yards wide. A professional soccer field is a rectangular 110 yards lon
Ksivusya [100]

Answer:

2200 Square Yards

Step-by-step explanation:

Dimension of the Youth Soccer Field = 110 yards long and 60 yards wide.

  • Therefore Area of the Youth Soccer Field = 110 X 60 =6600 Square Yards

Dimension of the professional soccer field =110 yards long and 80 yards wide.

  • Area of the professional soccer field = 110 X 80 =8800 Square Yards

The difference in their Area = 8800-6600=2200 Square Yards

Therefore, the professional soccer field has an area of 2200 Square Yards more than the youth soccer field.

Which expression is equivalent to -9(x – 4) – 6x?
kvv77 [185]
= -9(x – 4) – 6x
Multiply -9 by everything in parentheses first

= (-9*x) + (-9*-4) - 6x
= -9x + (36) - 6x

Combine like terms
= (-9x-6x) + 36

= -15x + 36

The middle choice is the answer:
-15x + 36

Hope this helps! :)

Triple my number add six and subtract my number twice I get my number plus three
liberstina [14]
Let the number be x.

Triple the number means 3x
add 6 means 3x + 6
subtract the number twice 3x + 6 - x - x
the result is the number plus 3 means that the result is x + 3

So, combining these into an equation, we get:
3x + 6 - x - x = x + 3

If we solve this equation for x, we will get:
x + 6 = x + 3
The x will cancel out and we will get : 6 = 3

Therefore, this is a false statement.
