Answer:

Step-by-step explanation:

arithmetic sequences can be written as

a_n = a_1 + (n-1)d\\

in this case

a_n = a_1 + (n-1)(-3)\\and\\17 = a_1 +(4-1)(-3)\\17= a_1 + (3)(-3)\\17= a_1 - 9\\a_1 = 26\\so\\a_n = 26 - 3(n-1)\\a_n = 26 -3n + 3\\a_n = 29 - 3n

23X-4=20 Help please
k0ka [10]
Isolate both terms with "x" to the left side

23x -(4-4) = 20 + 4

23x - 0 = 24

its impossible to divide both ways because of 0 and 23 with 24 cant divide each other

so your answer would be

x = 23 over 24 or 23/24

hope this helps :D.

Simplify 10(N + 3).<br><br> 10N + 30<br> 10N + 13<br> 10N + 3
Alika [10]
N+3 evaluates to N+3
Multiply 10 by N+3

Multiply 10 by each term in N+3 term by term.

This is the distributive property of multiplication.

Multiply 10 and N
Multiply 1 and N

The N just gets copied along.
10 × N = 10N

Multiply 10 and 3
10 × 3 = 30

10*(N+3) evaluates to 10N+30

***The final answer is 10N+30***

vivado [14]
There are several information's already given in the question. based on those information's, the answer can be easily determined.
Height of the box = h cm
Length of the box = 10 cm
Width of the box = 2h
Then
Volume of the box = Length * height * width
                              = 10 * h * 2h cubic cm
                              = 20h^2 cm^3
I hope that the above procedure is clear enough for you to understand and it has actually come to your desired help.
