Try the last one; it doesn't mention anything foreign.
Answer:
x = 5 and y = 22
Step-by-step explanation:
See attached image.
Answer:
none because they all correlate with each other and there are no obvious anomalies
Step-by-step explanation:
-a²-3b³+c²+2b³-c²
= -(3)² - (3×2)³ + (-3)² + (2 × 2)³ - ( -3)²
= 9 - 24 + 9 + 16 - 9
= 1
answer is 1.
= 4 (6) - 4 (√2) + √2 (6) - √2 <span>√2
</span>= 24 - 4√2 + 6√2 - 2
= (24 - 2) + (- 4√2 + 6√2)
= 22 + √2(- 4 + 6)
= 22 + √2 (2)
= 22 + 2√2
hope it helps
