I would substitute y = x^2
4y^2 -21y+20=0
8 x 64
=64 x 2 x 4
=128 x 2 x 2
=256 x 2
=512
There are 16 possible outcomes.
This is found by taking the number of possible outcomes for each toss, 2, and raising it to the 4th power (for 4 tosses):
2⁴ = 2*2*2*2 = 16
Answer:
27 m
Step-by-step explanation:
We know that ABC = 42 degrees
and side length BC = 24m
tan42 = 24m/a
a = 24/tan42
a = 26.65m
round to nearest whole number
= 27 m
