The answer is 900 because 20×9=180 and just multiply 180×5 and that equals 900.
1 7/12 becuase 2 neg is a neg, 1 neg and 1 pos is which is bigger in this case it is pos.
Solve the system by the elimination method.
2a + 3b = 6
5a + 2b - 4 = 0
multiply thru the top equation by 2
Multiply thru the bottom equation by 3
4a + 6b = 12
15a+ 6b = 12
Subtract and solve for "a":
11a = 0
a = 0
Solve for "b" using 2a + 3b = 6
2*0 + 3b = 6
b = 2
Factoring the left side of the equation
x(2x-5) = 150
x = 10 so the dimension are 10 and (2(10) - 5 = 15
length = 15 feet , width = 10 feet.
