How do you work out 84=6x+6

Mathematics

So, you do the operations on both sides. Subtract 6 from each side first, getting
84-6=6x
which is 78=6x
then, you divide both sides by 6 and you get 
78/6=x
which is 13

x=13

Hope this helped!

You are able to add multiply subtract and divide from both sides of the equation as long as you do it on both sides of the equation. so you want - 6 from both sides

84-6=6x+6-6

78=6x

and then you can divide both sides by 6

78/6 = 6x / 6

which equals

13 = x

Each packet of the cooking oil weighs 2/5th of a kilogram and one kilogram of the cooking oil costs $6.5. Sara went to the groce
Reika [66]

Answer:

C) $20.80

Step-by-step explanation:

1 kg of cooking oil = $6.5

1 packet of cooking oil =2/5 kg

If 1 kg of cooking oil = $6.5

2/5kg of cooking oil = $X

Cross Multiply

1kg × $X = 2/5kg × $6.5

$X = 13/5

$X = 2.6

Hence 2/5kg of oil cost $2.6

Since 1 packet of oil = 2/5kg of oil , 1 packet of oil cost $2.6

The amount she spent if she bought if she bought 8 packets of the cooking oil is calculated as:

1 packet of oil = $2.6

8 packets of oil =

$2.5 × 8

= $20.80

Therefore,if Sara bought 8 packets of oil, the amount she would spend = $20.80

a. x^4 + 4x^2 + 4

b. x = ∛-1 and -3

<h3>How to expand the expression</h3>

a.  Given

(x² + 2)²

First, we open up the bracket

(x^2 + 2) (x^2 + 2)

Multiply through

x^4 + 2x^2 + 2x^2 + 4

Collect like terms

x^4 + 4x^2 + 4

b. Let's factorize

x^4 + 4x + 3

Find the factors of 3 that are products of 4, they are 3 and 1

Use it to replace 4x as 3x and x

x^4 + 3x + x + 3

Let's make the expression two

(x^4 + 3x) (x+ 3)

Find the common factor

x^3(x + 3)+ 1(x+ 3)

So,

x^3 + 1 = 0 and x + 3 = 0

x = 3\sqrt{-1} and x = -3

Thus, x = ∛-1 and -3
