Step-by-step explanation:
The square root of a perfect square is a rational number.
Answer:
580
Step-by-step explanation:
(6x + 30)+(2x+6)= 180
8x +36= 180
8x= 144
X= 18
So 2x+6 = 42
And 6x+30 = 138
You would simply have to plug in, or substitute, the given values in the equations.
So, H=-5, W=2 and the problem is 4h-3w
To plug them in, your new equation would be 4(-5)-3(2) and simplify. So it becomes -20-6 which = -26.
And -26 would be your answer.
