Answer:
I got 38 and 11
Step-by-step explanation:
Easy
an=a1+d(n-1)
for the top one
d=4 and a14=46
a14=a1+4(14-1)
a14=a1+4(13
46=a1+52
-6=a
an=-6+4(n-1)
bottom one
d=-6
a12=-4
a12=a1-6(12-1)
-4=a1-6(11)
-4=a1-66
62=a1
an=62-6(n-1)
is it factorisatiom or solving equation?
Step-by-step explanation:
2m² + 2m - 12 divide the equation by 2
then: m² + m - 6
factorise: (m + 3)(m - 2)
solve m + 3 =0 or m - 2 =0
m= -3 or m = 2
