Answer:
There were 2 expressions I thought of it could be 10 x 5 or 10 + 10 + 10 + 10 + 10. I honestly hope this is the right answer because i'm only in 6th grade but hopefully it's correct.
Step-by-step explanation:
Yo mean sqrt 27 or √27
remember
√(xy)=(√x)(√y)
√27=(√9)(√3)=(3)(√3)=3√3
Answer:
hi now i ain't too sure but its C
Step-by-step explanation:
since we r adding it will move to the right side 2 blocks then we go down 5 since its minus
<span>In an arithmetic sequence, if a4 = 18 and a10 = 30, determine a1, d, and an.
Then write the first four terms of the sequence.
Use the formula L = A + (N-1)D, where L represents the nth term.
Then, based upon the given info,
18 = A + (4-1)D and 30 = A + (10-1)D.
The first equation boils down to 18 = A + 3D, so that A = 18 - 3D. Subst. 18-3D for A in the second equation: 30 = 18-3D + 9D. Then 12=6D and D = 2.

Use </span>A = 18 - 3D to determine the value of A. Recall that D=2.
Then A = 18 - 3(2), or A = 18-6, or A = 12.
Then L = A + (N-1)D becomes L = 12 + (N-1)(2).
First term is 12. Next is 14; next is 16; last is 18.
