Answer:
16
Step-by-step explanation:
a^2+b^2=c^2
a^2+12^2=20^2
144+a^2=400
a^2=256
a=16
Something like: the line goes through points (1,2) (3,4) and (11,12)
Answer:
Option A
Step-by-step explanation:
Weight of an apple = twice of the weight of a lemon
Weight of an apple = 2(weight of a lemon)
x = 2y ------(1)
x = weight of an apple
y = weight of a lemon
Number of apples in a box = 16
Weight of the apple box (A) = 16x
Number of lemons in another box = 24
Weight of the lemon box (B) = 24y
Therefore, 

[From equation (1)]


Option A will be the correct option.
