Answer:
No
Step-by-step explanation:
When you square a number, you chose a number and multiplying itself. If you did the square root of 25, you would get 5. However if you divided 25 by 2, you would get 12.5 which is NOT the square root.
7x - (25x^2 + 12x) = 7x - 25x^2 - 12x = -25x^2 - 5x
It is 7 opposite is different and absolute value would be 7 also it is always positive
Answer:
x = 12
Step-by-step explanation:
Complementary angles add up to have a sum of 90 degrees. We can create an equation and solve for x.
3x + 6x - 18 = 90
~Simplify
9x - 18 = 90
~Add 18 to both sides
9x = 108
~Divide 9 to both sides
x = 12
Best of Luck!
