Answer:
rose$7 shrub $11
Step-by-step explanation:
5r+3s=68
1r+14s=161
I will multiply the second by -5 to eliminate r variable
5r+ 3s= 68
-5r- 70s = -805
-67s = -737
Divide both by -67
s= 11
14*11=154
161-154 =7
5*7 + 3*11 = 68
35+33 = 68
7+ 14*11 = 161
7+154 = 161
You must know that : (a-b) ^2 = a^2 - 2ab + b^2 so let a=x and b=2, applying above formula you'll get f(x) = x^2 - 4x +4 + 4 =x^2 - 4x +8 Hope you got it ;-) Revert back if you still face any trouble.
