Sorry no answer just wanted to say your pfp is hot
Number 1:
9x^2 + 12x + 4 -> (3x + 2)^2
16x^2 + 24x + 9 -> (4x + 3)^2
2. x^2 + Bx + 64
B = (sqrt64) *2 = 16
3.
Solving equations like this requires completing the square, which has the first step of choice 4.
You have to enter them into a calculator and graph it on the calculator
Is the first number supposed to be $200,000? If it is then the increase is $50,000. Divide $50,000 by the original cost of the house (200,000) which is 0.25. Multiply that number by 100 to get % and the increase is 25%.
12=X
4x-10=5x-22
+22 +22
4x+12=5x
-4x -4x
12=x
