Answer:
36
Step-by-step explanation:
![\sqrt[4]{16 \times 27 \times 54 \times 72 \: \: } \: = 36](https://tex.z-dn.net/?f=%20%5Csqrt%5B4%5D%7B16%20%5Ctimes%2027%20%5Ctimes%2054%20%5Ctimes%2072%20%5C%3A%20%20%5C%3A%20%7D%20%20%5C%3A%20%20%3D%2036)
Answer :A)-2
Step-by-step explanation: If you multiply B; x + 9y =10 by -2 you will have -2 x+ -18y= -20. Then when you add B with a 2x + 8y = 5
-2x +-18y=-20
=0 +-10y=-15
Line equation is
y - y1 = m * (x - x1)
y - (-7) = (-5) * ( x - 1)
y + 7 = -5x + 5
y + 5x + 2 = 0
