Answer:
the answer is 20,21,29 because
20 times 20 is 400
21 times 21 is 441
and 29 times 29 is 841
the formula to ge tthe answer is a^2 + b^2 = c^2
20^2 + 21^2= 29^2
then plug the rest in
400+441= 841

Answer:
208 ft
Step-by-step explanation:
in order to do this we need to find the area of the retangle:
(l x w) 14x20= 280ft
then the area of the rectangle:
a^2 + b^2 = c^2 ( hypotenus lenght )
c= 8.5
now we can plug in to find the area of the triangle, which is 12 (11.99)
then the area of the trapezium= 60
finally we can find the answer
280 - (60+12)= 208 ft :)
Answer:(2x+5)(x+5)=0
Step-by-step explanation:
2x^2+15x+25=0
Factorise we have
2x^2+10x+5x+25
(2x^2+10x)+(5x+25)=0
2x(x+5)+5(x+5)=0
(2x+5)(x+5)=0
