50 g
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
So this is a BIDMAS question so first you do what’s in the brackets so you have (1-9x1-4) and you have to do the multiplication first out of that to get (1-9-4) which is -12 so then you have overall 36 / -12 + 1 + 2 so you have to do the division first so do 36/-12 to get -3 and you have -3 + 1 + 2 which is 0 so your answer is 0.
First one
20=n/5+10
minus 10 both sides
10=n/5
times 5 both sides
50=n
2.
hmm
expand
p(x)=2x^2+5x+3-3x-3n
p(x)=2x^2+2x+3-3n
it looks like the coefients of the x terms are divisble by 2
because
if we have
p(x)=2(something)
the p(x) is divisible by 2
therefor that factor is 2 or -2
find what value of n works
so
3-3n=a multipule of 2
we are given
-3,-2,0,2
try each
3-3(-3)=3+9=12, that's divisble by 2
3-3(-2)=3+6=9, that's not divisible by 2
3-3(0)=3, that's not divisble by 2
3-3(2)=3-6=3, that's not divisble by 2
the onnly one that woks is when n=-3
answer is A
