What is the measure of the hypotenuse

THE HYPOTENUSE IS 5 CM

hyp² = side² + side²

= 3² + 4²

= 9 + 16

= 25

= √25

= 5 cm

hypotenuse = 3 squared + 4 squared

which equals 25

then you radical 25 which equals 5

so the hypotenuse equals 5

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
