4x + (28x -2) is not an equation. It doesn't ask a question, so it doesn't need answering or solving. The expression stands for a number. In order to know the number, you first have to know what number 'x' is.
68 + 28x - 28 = 236 28x + 68 - 68 -28 + 28 = 236 - 68 + 28 28x = 196 x = 7
I assume that is (7x-2)^2 = 16 (7x-2)(7x-2) = 16 49x2 -28x +4 = 16 49x2-28x-12=0 use quadratic formula x = ( -b +/-sqrt(b2-4ac) ) /2a x = -2/7
The sum is 28x
7x+7=28x 28x-7x=7 21x=7 x=3
In order to solve this equation you need to know what -28x-2 equals. If you were to assume it was 0 then x = 0.071 rounded
x=35
4x + (28x -2) is not an equation. It doesn't ask a question, so it doesn't need answering or solving. The expression stands for a number. In order to know the number, you first have to know what number 'x' is.
68 + 28x - 28 = 236 28x + 68 - 68 -28 + 28 = 236 - 68 + 28 28x = 196 x = 7
That depends on the - or + values of 28x and 980 which have not been given

I assume that is (7x-2)^2 = 16 (7x-2)(7x-2) = 16 49x2 -28x +4 = 16 49x2-28x-12=0 use quadratic formula x = ( -b +/-sqrt(b2-4ac) ) /2a x = -2/7
49x2+28x+4 = (7x+2)(7x+2) when factored
what is -12X squared +28X - 15? i figured it out myself. its (-6X + 5)(2X - 3).
The GCF is 4x.
The sum is 28x
Suppose the total length was 1+x minutes.Then cost = 55 + 28x = 727So 28x = 272, therefore x= 24.So the call length was 25 minutes.Suppose the total length was 1+x minutes.Then cost = 55 + 28x = 727So 28x = 272, therefore x= 24.So the call length was 25 minutes.Suppose the total length was 1+x minutes.Then cost = 55 + 28x = 727So 28x = 272, therefore x= 24.So the call length was 25 minutes.Suppose the total length was 1+x minutes.Then cost = 55 + 28x = 727So 28x = 272, therefore x= 24.So the call length was 25 minutes.
