Answer:
b² + c² = 47
Step-by-step explanation:
Expand (b + c)² = 61
⇒ (b + c)(b + c) = 61
⇒ b² + 2bc + c² = 61
Substitute bc = 7 into b² + 2bc + c² = 61:
b² + 2(7) + c² = 61
b² + 14 + c² = 61
To determine b² + c² simply subtract 14 from both sides of the equation:
b² + c² = 47
Answer:

m * 2 + 2 = j
Answer:
Mark is 8
Johnny is 18
Step-by-step explanation:
m * 2 = j - 2
26 - 2 = 24
24 / 3 = 8
8 * 2 + 2 = 18
There are many possible solutions. As long as it’s a number greater than 4 it’s acceptable.
