-a=2\times 6−a=2×6
-a=12−a=12
a=-12a=−12
Therefore, the value of a will be -12.

Solve : 3a + 4/ 2 - 6a = -2/5
Answer:
The solve of this equation is X = 4,06
Step-by-step explanation:
To solve this formula:
2 ( X² - 16) = 1
You must use the distributive law of multiplication, thus:
2X² - (16×2) = 1
2X² - 32 = 1
2X² = 1 + 32
X² = 33/2
X² = 16,5
X = √16,5
X ≈ 4,06
Thus, the solution of this equation is:
<em>X ≈ 4,06</em>

Scale factor shows by how much the original model has been multiplied or divided by to get the measurements of the drawing .
In this case the ladybug is 8 mm long but drawing length is 2 cm.
Let’s convert both into the same units
2 cm -20 mm
Original - 8 mm
Painting -20mm
X - scale factor
20 = X * 8
X = 20/8 = 2.5
The ladybug has been multiplied/ enlarged by a scale factor of 2.5 to draw the painting
Answer:
40.5 square inches
Step-by-step explanation:
Rectangle consists of two identical squares.
So, if the sides of square = x,
Then, Width of rectangle = x &
Length of rectangle = x +x = 2x
Perimeter of rectangle = 27 inches
2*(length + width) = 27
2*( 2x + x) = 27 {Combine like terms]
2* 3x = 27
6x= 27 {Divide both sides by 6}
x = 27/6
x = 4.5
Width = x = 4.5 inches
Length = 2x = 2*4.5 = 9 inches
Area of rectangle = length *width
= 4.5 *9
= 40.5 square inches
