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)

How do you solve st+3t=6
bonufazy [111]
You will factor out the common factor of t if you are solving for t. you will then divide both sides by (s+3) to make t the subject of the formula. for this question you can only get t in terms of s.
so:
st+3t=6
t(s+3)/(s+3)=6/(s+3)
t=6/(s+3)

if you are required to solve for s then you are going to subtract 3t from both sides. you can factorise 6-3t .you will then divide both sides by t to isolate s.for this question you can only get s in terms of t.so:

st+3t-3t=6-3t
st/t=2(3-t)/t
s=2(3-t)/t
