Answer:
Laura is 8
Step-by-step explanation:
let Laura's age now be x then Daniel's age is 2x
4years ago
Laura was x - 4 and Daniel 2x - 4, thus
2x - 4 = 3(x - 4) ← 3 times Laura's age
2x - 4 = 3x - 12 ( subtract 2x from both sides )
- 4 = x - 12 ( add 12 to both sides )
8 = x
Thus Laura is 8 years old

3(x+1)=3x+3
-2(x-1)+6=-2x+2+6=-2x+8
3x+3=-2x+8
X=1 because 3(1)+3=6 and -2(1)+8=6
Polynomials are algebraic expressions that contain more than two terms. AN example would be: f(x) = x^3 + x^2 + x +1. This equation contains three terms, with the 3rd degree as its highest term. It also means that the graph passed three x-intercepts. This depends in the highest degree. So, the first thing you do is plot the intercepts because for sure, the graph will pass there.
