Answer:
x = 4√7
Step-by-step explanation:
You can use the pythagorean theorem which is a² + b² = c²
if you plug it in, it would be...
x² + 12² = 16²
x² + 144 = 256, subtract 144 to both sides
x² = 112, square root both sides to make x by itself.
x = 4√7
1/2* N= 1/3
⇒ N= (1/3)/ (1/2)
⇒ N= (1/3)* (2/1)
⇒ N= 2/3
The final answer is N= 2/3~
The expansion of the binomial:
( 2 x² + y² ) ^4 =

=
You basically multiply the number outside the parentheses by everything inside.
So 2 × 6x = 12x,
2 × 5 = 10,
2 × 2y = 4y.
So your answer is 2(6x + 5 + 2y).
Answer:
its the first question i think it might be wrong idk
Step-by-step explanation:
because when you find the area you multiply two sides so you have to add 10 and 5 and then multiply it by 18
