PLS HELP!! AND HURRY!! Find an expression for the nth term ( tn ) in each of the following sequences:

fiasKO [112]

If the pattern continues, so that each term is separated by a distance of 3, then the sequence is given by the recursive rule

$\begin{cases}a_1=1\\a_n=a_{n-1}+3&\text{for }n>1\end{cases}$

From this definition, we can write $a_n$ in terms of $a_1$ :

$a_2=a_1+3$

$a_3=a_2+3=(a_1+3)+3=a_1+2\cdot3$

$a_4=a_3+3=(a_1+2\cdot3)+3=a_1+3\cdot3$

$a_5=a_4+3=(a_1+3\cdot3)+3=a_1+4\cdot3$

and so on, up to

$a_n=a_1+(n-1)\cdot3$

(notice how the subscript on a and coefficient on 3 add up to n)

$a_n=1+3(n-1)=3n-2$

Which expressions are equivalent to (5g+3h+4)\cdot2(5g+3h+4)⋅2left parenthesis, 5, g, plus, 3, h, plus, 4, right parenthesis, do

hichkok12 [17]

Answer:

C None of the above

Step-by-step explanation:

Here are the required options

Choose all answers that apply

A (5g+3h).8

B (5g+3h).6

C None of the above

Given the expression;

(5g+3h+4).2

Expand

(5g+3h+4).2

= 2(5g+3h+4)

= 2(5g) + 2(3h) + 2(4)

= 10g+6h+8

Checking option A;

(5g+3h).8

Expand

= 8(5g+3h)

= 8(5g) + 8(3h)

= 40g+24h

Checking option B:

(5g+3h).6

Expand

= 6(5g+3h)

Using the distributive law;

= 6(5g) + 6(3h)

= 30g+18h

Since none of the expressions for A and B is equivalent to 10g+6h+8, hence NONE of the options are correct

Diana paints 150 fence posts and chuck paints 130 fence posts. Diana paints 10 more fence posts than chuck. How many fence posts

statuscvo [17]

Complete Question

The complete question is shown on the first uploaded image

Answer:

Step-by-step explanation:

From the question we are told that

The relationship is $\frac{150 }{d} = \frac{130}{c}$

The number of fence post painted by chuck is $l = 130$

The number of fence post painted by Diana is $k = 150$

can paint 10 fences more than chuck so let say the of fence painted in an hour by chuck is $g$

Then the number of fence post painted by Diana in one hour is

$f = g+ 10$

$\frac{150 }{ g + 10 } = \frac{130}{g}$

$130 g + 1300 = 150g$

$g = 65 \ m$
