Step-by-step explanation:
LOL
Your answer is no solution (because a negative square root doesn't exist)
first, you divide all sides by five and then take b, half it then square it
Answer is number 2
F(3)= (3-1)^2+ 3(3)=4+9= 13 so the first option is wrong
F(-2)= (-2-1)^2+ 3(-2)= 9-6=3 third options is wrong
F(-15)= (-15-1)^2 +3(-15)= 256-45= 211 fourth option is wrong
Answer:
21.2 or 15 sqrt of 2 (PETHAGOREOM theorem)
Step-by-step explanation:
a^2+b^2=c^2
20^2+5^2=C^2
400+25=C^2
450=C^2
sqrt 450=
15 sqrt of 2 or 21.2
