Answer:
9h² + 42hk + 49k²
Step-by-step explanation:
Given
(3h + 7k)²
= (3h + 7k)(3h + 7k)
Each term in the second factor is multiplied by each term in the first factor, that is
3h(3h + 7k) + 7k(3h + 7k) ← distribute both parenthesis
= 9h² + 21hk + 21hk + 49k² ← collect like terms
= 9h² + 42hk + 49k²
Answer:
6h+14k
Step-by-step explanation:
Multiply 2by 3h which gives 6h then multiply 7k by 2 which gives 14k.
Since 6h and 14k are not like terms u cannot add so your answer will be 6h + 14k.

Answer:
If A=10, then 2a+3=23
Step-by-step explanation:
2x10=20
20+3=23
(x+51)+(x+59)+84=180 (Sum of angles in a triangle)

x=-7
Angle A: x+51=-7+51=44°
