Step-by-step explanation:
When f(x) = f(x - 4), 3x² = 3(x - 4)².
=> x² = (x - 4)², x = -(x - 4), 2x = 4, x = 2.
The x-value is 2.
Step-by-step explanation:
Answer:
x = 1.5
Step-by-step explanation:
using the sine ratio in the right triangle and the exact value
sin60° = , then
sin60° = = = ( cross- multiply )
2x = 3 ( divide both sides by 2 )
x = 1.5
area of the parallelogram is: b x h
12 x 4 = 48 (d)
