Question

10x
1. Ifx=2, y=4, find the value of:
(a) x+4y 2+u(b) -x-y



​

Answer 1

Answer:

u(b) = -60

Step-by-step explanation:

x+4y²+u(b) -x-y = 0

put x = 2 and y = 4

2 + 4(4)² + u(b) - 2 - 4 = 0

2 + 4(16) + u(b) - 6 = 0

2 +    64 + u(b) - 6 = 0

u(b) + 66 - 6 = 0

u(b) + 60 = 0

u(b) = -60

I hope it help you !!!

have a nice day!!
