Consecutive integers are 1 apart
they are
x,x+1,x+2
the sum of their squares is 194
x²+(x+1)²+(x+2)²=194
expand
x²+x²+2x+1+x²+4x+4=194
x²+x²+x²+2x+4x+1+4=194
3x²+6x+5=194
minus 5 from both sides
3x²+6x=189
3(x²+2x)=189
divide both sides by 3
x²+2x=63
minus 63 from bot sides
x²+2x-63=0
what 2 numbers multiply to get -63 and add to get 2
-7 and 9
(x-7)(x+9)=0
set each to zero
x-7=0
x=7
x+9=0
x=-9
for x=7
x+1=8
x+2=9
for x=-9
x+1=-8
x+2=-7
the integers are 7,8,9 or -9,-8,-7
Answer:
2 in
Step-by-step explanation:
Answer:
ok so first we have to do whats in the brackets then we have to do to exponits so first
(-0.00024414062divided by 0.00390625)^2
-0.06249999872^2
-0.00390624984
Hope This Helps!!!
Overtime, weather can shape our land in ways such as water levels rising or ice melting. Heat that is in the earth's molten core can over time cause lands to move (ex. Continental drift) and much more. Water levels are a problem mainly because of the rapid human population growth rate. In the future, weather could change the way that we live our lives.
