Answer:multiply both numbers in the parenthesis by the number outside:

2n+4 +10=4n+20

add all like terms

2n+14=4n+20

subtract both sides by 14 and 4

2n-4n = 20 - 14

add or subtract like terms

-2n = 6

divide both sides by -2

n = -3

Step-by-step explanation:

Please find the correct question in the attached file.

In point A:

An order of 5 items shall be placed in a total of 6 different ways.

(w for cars and ts and tricycles to be used)

$\to 5w=20 wheels\\\\\to 4w+1t= 19 wheels\\\\\to 3w+2t=18 wheels\\\\\to 2w+3t=17 wheels\\\\\to 1w+4t= 16 wheels\\\\\to 5t=15 wheels\\\\$

In point B:

2 waggons so more tyres would be required if they ordered any more waggons.

$work: \\\\ \to 2 \times 4=8 \\\\ \to 3 \times 3=9 \\ \\ \to 8+9=17$

To the right are the outcomes that are possible when a couple has three children. assume that boys and girls are equally likely

hoa [83]

The all possible eight outcomes of boy or girl birth when a couple have three children is

(GBB) , (GBG), (GGB) , (GGG), (BBG), (BGB), (BGG), (BBB)

Where B represents boy and G represents Girl

The probability that having exactly 1 girl is

= Number of outcomes with one girl / Total numbers of outcomes

Now Number of outcomes with only one girl = GBB, BGB, BBG = 3

So the probability will be

The probability that having exactly 1 girl is = 3/8 = 0.375

The probability that when a couple has three children, there is exactly 1 girl is 0.375

Given the function f(x)=3x-1, find f(x+2)

astra-53 [7]

Answer:

f(x + 2) = 3x + 5

Step-by-step explanation:

when we are given the function f(x) = 3x - 1 and asked to find f(x +2), we are basically plugging in x + 2 for x in the original function. its the input in the function

f(x + 2) = 3(x + 2) - 1 < distribute 3 into x + 2

f(x + 2) = 3x + 6 - 1 < combine like terms

f(x + 2) = 3x + 5

the solution to f(x + 2) is 3x + 5
