Answer:
-14
Step-by-step explanation:
The like terms in this equation is y^2 and -7y^2 so combining the two the equation becomes:
xy-6y^2
Then we substitute the values in:
5×2-6×2^2 = -14
if y =50 then x = 10 ......... option d
According to Lara value of w=44
So, D=2w+50
Put value of w=44
D=2(44)+50
D=88+50
D=138
Your answer is 138.
