Answer:
Step-by-step explanation:instead, try making the subscripts and superscripts stand out:
n-1
a = a * r
n n-1
Believe me, it's worth the extra work to do this!!
Given the sequence -3, -6, -12, -24, you can easily see that the first term,
a is -3. The common factor is 2. Note how (-3)*2=-6, and so on.
1
So, a = -3 and r=2.
1
So the formula for this geometric sequence is
n-1
a = -3*2
n
Make it so that the fractions have common denominators. 12 is a common denominator we can use.
5/6= 10/12 1/4= 3/12
Multiply both numbers by 2. Multiply both by 3.
Now, add.
4 10/12+ 5 3/12= 9 13/12
Simplify.
10 1/12.
I hope this helps!

75 divided by 6 is 12.5
since you cant have half a cartoon you need 13 cartoons
you round 12.5 up to 13
The answer is c. a rotation and translation
4 with an exponent of 7 is like saying 4*4*4*4*4*4*4
7 with an exponent of 4 is like saying 7*7*7*7
