Step 1: Distribute. On the right side, you should get =2x-4
Step 2: Add all common bases. You should get 4x-5 on the left side
Step 3: Add on each side. For example, add five to each side of the equation. Your equation should look like this; 4x= 2x+1
Step 4: Subtract each x number by 2x. Your equation should be; 2x=1
Step 5: Divide each side by two. Your answer should be x=1/2 or x=0.5
Hope this helped!

Answer:
Distance = 73 m
Step-by-step explanation:
Given that,
The length of a rectangle = 48 m
The width of a rectangle = 55 m
We need to find the diagonal distance. We can use the Pythagoras theorem to find it.
So, the required distance is equal to 73 m.

Hi, There!
Option B 125% Is the Most Accurate Answer
Step-by-step explanation:
Circumference is the distance around a plane shape. So, it also measures length.
Length and area of two similar shapes are related by the formula
Where the A in both cases represents area and the L represents length. But here the Ls will represent circumference.
Since the circumference of the circle increased by 50%, then the new circumference becomes
Now subtracting from the original area then
This means that the area was increased by 1.25, which means 125%
Hence option B is the correct answer
Hello!
To find the value of b, we need to use the Law of Sines. The law states,
sin A / a = sin B / b = sin C / c.
We are given these values: sin A = 55 degrees, side a = 8 cm, sin C = 82 degrees.
Since angle B is not given, we have to find it ourselves. We can find the measure of angle B by subtracting both the given angle values from 180 degrees because every triangle is equal to 180 degrees.
180 - 55 - 82 = 43 | The measure of sin B = 43 degrees.
sin (55) / 8 = sin (43) / b (multiply both sides by b)
0.10239... · b = 0.68199... (divide both sides by 0.10239...)
c = 6.6607...
The measure of side b is equal to about 6.7 centimeters.
