Step-by-step explanation:
Answer:
A=4cm² is the correct answer
Given:

To find:
The value of x.
Solution:
We have,

By cross multiplication, we get


Isolating variable terms, we get


Divide both sides by 4.


Therefore, the solution of the given equation is x = 0.25.
Answer:
x = -9
Step-by-step explanation:
2x + 8( x + 3 ) = 3( x - 13 )
Dstribute;
2x + 8 ( x + 3 ) = 3 ( x - 13 )
2x + ((8)(x)) + ((8)(3)) = ((3)(x)) - ((13)(3))
2x + 8x + 24 = 3x - 39
Combine like terms;
2x + 8x + 24 = 3x - 39
10x + 24 = 3x - 39
Inverse operations;
10x + 24 = 3x - 39
-3x -3x
7x + 24 = -39
-24 -24
7x = - 63
/7 /7
x = -9
