Answer:
y =
Step-by-step explanation:
to get the hypotenuse:
use the Pythagorean theorem:
a² + b² = c²
where a = 19, b = 8.2 c = y
plugin values:
19² + 8.2² = y²
y =

Answer:
Step-by-step explanation:
Work via factoring by groups:
!) re arrange the terms as follows:
then extract the common factor for the first two terms (a), and separately the common factors for the last two terms (3 b):
Now notice that the binomial factor (a-5 b) is in both expressions, so extract it:
which is the final factorization.
