The given dimensions that we have in this question are 105 and 45
<h3>How to solve for the dimensions</h3>
We have 2(l + b ) = 300
l + b = 300/2
l + b = 150 ----- 1
The fencing would be
30l + (6b + 6b) = $3690
30l + 12b = 3690 ---- 2
We have to solve this through the use of simultaneous linear equation
The calculator that has been used to solve this is the simultaneous linear equation calculator.
This would give us the values of 105 and 45.
We have to conclude that the dimensions are 105 and 45

Answer:
- (x, y) = (8, -1)
- (x, y) = (7, 10.5)
Step-by-step explanation:
1. You can use the expression for y to substitute into the first equation:
2x +4(1/4x -3) = 12
2x +x -12 = 12 . . . . . . eliminate parentheses
3x = 24 . . . . . . . . . . . add 12; next divide by 3
x = 8 . . . . . matches choice C
__
2. You can use the expression for y to substitute into the second equation:
x -2(2x -3.5) = -14
-3x +7 = -14 . . . . . . eliminate parentheses
21 = 3x . . . . . . . . . . add 3x+14; next divide by 3
7 = x . . . . . matches the third choice
_____
When the answer choices are sufficiently different, you only need to find one value to determine which is the correct choice. (If you want to check your work further, you can substitute the other answer value into the two equations to see if it works.)
Answer:
(7,3)
Step-by-step explanation:
What are factors of -40?
(-20)(2)
(-10)(4) (sum of these factors is 6, which is not what we wanted)
(-5)(8) = -40 and the sum of the factors (-5) and (8) is 3.
{-5, 8} is the list of factors of -40 that add up to 3.
