The height of the triangle = 4cm</h2>
Step-by-step explanation:
Given, area of the triangle = 10 
Let the height of the triangle be h cm
Given, the base b is 3 cm less than twice its height.
b = 2h - 3 ... (1)
By formula, area of the triangle = 
bh .. (2)
substitute (1)in (2), we get
Area = (2h-3) h
10 = (2h-3) h
20 = 
- 20 = 0
solving the equation, we get x = 4, -2.5
The height of the triangle = 4cm
Answer:
4.2
Step-by-step explanation:
surface area of a cube
6l
Let the number of copies that must be sold to break even be x, then
3255 + 2.90x = 13.75x
13.75x - 2.90x = 3255
10.85x = 3255
x = 3255/10.85 = 300.
Therefore, 300 <span>copies must be sold to break even</span>
X=12 because 4x=7y so if there were 21y then it would be 4 * 3 which is 12<span>

Answer:
To determine the answer of the question above, perform the operation that will allow you to get the value of x. For the given above perform the following,
x + 14 = 63
x = 63 - 14 = 49
Thus the solution of the given equation is x = 49. The answer is 49.
