X = 4, -2 that should be the roots(zeros) of the function.
First, expand the equation:
10x + 20 = 5x + 40
Now, isolate the variables:
10x - 5x = 40 - 20
Add or subtract:
5x = 20
Divide both sides by 5:
x = 4
There you have it!
Answer:
they are 2 lines that look ;like this =
Step-by-step explanation: the 2 lines of the equal sign are parallel
Scale Factor = 1 : 12
It means, for every 12 centimeters, it is 1 centimeter in the model
The depth of Tower in model = 32 cm
In real, It would be: 32 * 12 = 384 cm
We know, 1 m = 100 cm
So, 384 cm = 384/100 = 3.84 m
In short, Your Answer would be: 3.84 meter
Hope this helps!
