Answer:

33 degrees

Step-by-step explanation:

It is 21 degrees inside the command center and negative 12 degrees outside.

You want to find the difference between these, which means you want to subtract.

That will look like:

21 - (-12) = ?

since you have two negative signs next to each other, they will cancel each other out.

Our new equation:

21 + 12 =

21 + 12 = 33

The difference between these two temperatures is 33 degrees.

C(n)=-6+5(n-1)<br> find the 8th term in this sequence
Goryan [66]

Answer:

29

Just replace n by 8 ===> C(8) = -6+5(8-1) = - 6 + 5x7 = -6+35 = 29

Step-by-step explanation:

We have been given a sequence formula. We are asked to find the 8th term of our given sequence.

We know that an arithmetic sequence is in form A_n=a_1+(n-1)d, where,

A_n=\text{ nth term of sequence},

A_1=\text{ 1st term of sequence},

n = Number of terms in sequence,

d = Common difference.

To find the 8th term of our given sequence, we will substitute n=8 in our given formula.

c(n)=-6+5(n-1)

c(8)=-6+5(8-1)

c(8)=-6+5(7)

c(8)=-6+35

What type of triangle, if any, can be formed with angle measures of 32, 126, and 32
GalinKa [24]

Answer:

No triangle

Step-by-step explanation:

All triangles must have angles that measure up to 180 degrees. When you add 32, 32, and 126 you get 190. That means that no triangle can be formed.

I hope this helps!
