The value of x would be 5 for the model 2x+4.
Rearrange unknown terms to the left side of the equation,
Combine like terms
By calculating the sum or difference : -x = -5
Lets divide both sides of the equation by the resulting coefficient 5
So x = 5

The radius of the given circle is 2.84 units
Step-by-step explanation:
Step 1 :
Given
The perimeter of a quarter table is 17.85
We need to find the circle's radius.
Step 2 :
The circle's perimeter is given by the formula, 2 
r where r represents the circle's radius
So from this we have ,
2 r = 17.85
We can determine the radius by dividing the perimeter value by 2
= > r = 17.85 divided by 2 r
= 2.84 [ taking = 
]
Step 3 :
Answer :
The radius of the given circle is 2.84 units
Answer:
The answer is 35.5 square units
Step-by-step explanation:
The shape represents a rectangle, a small triangle removed from it at the upper right corner and a bigger triangle is attached to it at the upper left corner.
We get this formula:
A(shape) = A(rectangle) - A(small triangle) + A(big triangle)
SO LET'S FIND EACH!
A(rectangle)= length x width
length= 8 units
width= 4 units
We get:
A(rectangle) =8x4= 32 square unit
A(small triangle)= (base x height)/2
base= 1 unit
height= 1 unit
We get:
A(small triangle) = (1x1)/2 = 1/2 = 0.5 square units
A(big triangle)= (base x height)/2
base= 2 units
height= 4units
We get:
A(big triangle)= (2x4)/2 = 8/2 = 4 square units
For the final result:
A(shape) = 32 - 0.5 + 4 = 35.5 square units
