Isolate the g
w = 7 - √g
Do the opposite of PEMDAS, first subtract 7 from both sides
w (-7) = -√g + 7 (-7)
w - 7 = -√g
multiply -1 (as -√g is the same as -1√g) to both sides
-1(w - 7) = √g
-1w + 7 = √g
to get rid of the square root, you must square both sides
Note: -1w is the same as -w
Note: you are squaring all the terms on the other side, not just one.
(-w + 7)² = (√g)²
g = (-w + 7)²
g = (-w + 7)(-w + 7) (note, this can be the answer your teacher wants, or g = (-w + 7)² )
Use the FOIL method (First, Outside, Inside, Last)
(-w)(-w) = w²
(-w)(7) = -7w
(7)(-w) = -7w
(7)(7) = 49
g = w² - 7w - 7w + 49
simplify (combine all like terms)
g =w² - 7w - 7w + 49
g = w² - 14w + 49
g = w² - 14w + 49 is your answer

Answer:
850- 475= 375 increase over 2 months.
375 ÷2= $187.50
You need to multiply 8.7 by 3.14.You should get 27.318
Since the first term is x², you know that each group will begin with x. To find the second part of the groups, you need to find two numbers that add up to 10 and multiply to 25. You can do this by listing all the factors of 25 until you find a set that adds to 10.
25 x 1
5 x 5
-5 x -5
The second terms in your groups will be -5 and -5.
(x - 5) (x - 5) This can be simplified to (x - 5)².
