How do you work out 84=6x+6

2 answers:

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

Area triangles? it says show work so pls do

$\large{\underline{\underline{\pmb{\sf {\color {blue}{Solution:}}}}}}$

Given,

Area = 225 yd²

Base = 30 yd

Height = [To be calculated]

To find:

The height of the given triangle.

We know that, area of a triangle is:

$\frac{1}{2} \times (b \times h) \\ \\ \leadsto \frac{1}{2} \times (30 \times h) \\ \\ \leadsto \frac{1}{2} \times 30h \\ \\ \leadsto \frac{1}{ \cancel{2}} \times \cancel{30}h \\ \\ \leadsto1 \times 15h \\ \\ \leadsto \: h = 15 \: yd$

Therefore, the require height is 15 yd.

$\green\star$ Proof:

$\frac{1}{2} \times (b \times h) \\ \\ \leadsto \frac{1}{2} \times (30 \times 15) \\ \\ \leadsto \frac{1}{ \cancel{2}} \times \cancel{450} \\ \\ \leadsto1 \times 225 \\ \\ area = 225 {yd}^{2}$

$\boxed{ \frak \red{brainlysamurai}}$

Using the information in the customer order, determine the length and width of the garden. Enter the dimensions. ↓

SashulF [63]

Answer:

Length: 14 feet Width: 1 foot

Step-by-step explanation:

This is the only way to have a rectangle that has a perimeter of 30 feet, and an area of 14 feet.

For perimeter:

14 + 14 = 28

1 + 1 = 2

2 + 28 = 30

These dimensions have a perimeter of 30.

For area:

14 x 1 = 14

These dimesnions also have an area of 14.

So, 14 and 1 are the correct dimensions!
