Answer:
pythagorean theorem=a squared + b squared =c squared
where c is the hypotenus(the longest part)
Step-by-step explanation:
16 squared = 8 squared +....
16 ×16=256=8×8=64 + y
256_64=192
sq. root of 192=13.85
y=180_90=90
90÷2=45
y=45
z=45
x=13.85cm

Yes
x=0; x=-2
so first you do (x+2)^2 which is x^2+2x+4
4x^2 +8x +16 = 16
Subtract 16 from both sides
4x^2 +8x = 0
factor out 4x:
4x(x+2) = 0
15
