Answer:
a) v=6
b) s= u^2 - v^2 : -2a
Step-by-step explanation:
v^2=u^2+2as
u=12, a=-6, s=9
a)
(12)^2= 12 * 12= 144
v^2=u^2+2as
v^2=(12)^2+ 2*(-6)*9
v^2=144+(-12)*9
v^2=144+(-108)
v^2=36
v=6
b)
v^2=u^2+2as
-2as=u^2 - v^2
s= u^2 - v^2 : -2a
check for s
s= 144 - 36 : -2(-6)
s= 108 : 12
s=9 (equal vs the given)
Answer:
x is 13
Step-by-step explanation:
x-2=11
then x = 11 +2
since the negative 2 will be crossing over the equal sign to turn positive
x= 13
