Answer:
x=-14
Step-by-step explanation:
-2(x-8)+4x= -12
-2x+16+4x=-12
2x=-28
x=-14
Answer:
x = -6
Step-by-step explanation:
Let the number be x
<u>Condition:</u>
=> 10-3x = x+22
<u><em>Let's Solve it:</em></u>
=> -3x-x = 22-10
=> -2x = 12
<em>Dividing both sides by -2</em>
=> x = -6
Answer:
2 integers/???
Step-by-step explanation:
The perimeter of these can be found by adding length and width and then multiplying by two.
Rectangle A: (with all of the variables already doubled)
2x + 16 + 2x - 2
2x + 2x + 16 - 2
4x + 14
So rectangle A's perimeter is 4x + 14.
Rectangle B: (Still with all the variables already doubled)
8x + 10 + 6x - 4
8x + 6x + 10 - 4
14x + 6
So rectangle B's perimeter is 14x + 6
And now to subtract the two.
(7x + 3) - (4x + 14)
14x + 6 - 4x - 14
14x - 4x + 6 - 14
10x - 8
So it would be C.
