Let us rewrite the expression so that the like terms are next to each other.

Combine the coefficients.



The area of a square is its side length squared. So the side length of the square squared is 42, so the side length of the square is sqrt(42). The perimeter of the square is 4 times the side length, or 4sqrt(42), which is approximately 25.92.
Answer:
19.5
Step-by-step explanation:
I'm presuming the scale factor's 1.75/1
14*1.75=21.5
21.5-2=19.5
Your answer would be x = -15.8994.
To get this, you first add 7 to each side making the equation -4.818 = x/3.3
Then, you would need to multiply each side by 3.3 to get x by itself.
Your answer would be -15.8994.
