Answer:
165.
Step-by-step explanation:
The nth term is an = a1 + (n - 1)d.
The common difference (d) is 7 and the first term (a1) is -3, so the 25th term
= a25 = -3 + (25-1)*7
= =3 + 24*7
= 165.
I think the answer is 180 but im not 100% on that
Answer:
y = 11
Step-by-step explanation:
Since our plane is parallel to the xz plane, the x and z are independent of each other, i.e. they could be anything. So xz plane has an equation of y = 0. So if this plane is located 11 units to the right of the xz plane then its equation must be y = 11.
