I guess you mean 5m and 14m are the lengths of 2 sides of the triangle.
If the length of any side is equal or greater than the sum of the other 2 sides then you can;t make a triangle.
So for example 19 cannot the answer because 19 = 5 + 14 . No triangle can be formed with sides that measure.
and 38 is greater than 14 + 5 so its cant be C.
The answer is A
Simplifying
5x + 7 = 2x + 4
Reorder the terms:
7 + 5x = 2x + 4
Reorder the terms:
7 + 5x = 4 + 2x
Solving
7 + 5x = 4 + 2x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2x' to each side of the equation.
7 + 5x + -2x = 4 + 2x + -2x
Combine like terms: 5x + -2x = 3x
7 + 3x = 4 + 2x + -2x
Combine like terms: 2x + -2x = 0
7 + 3x = 4 + 0
7 + 3x = 4
Add '-7' to each side of the equation.
7 + -7 + 3x = 4 + -7
Combine like terms: 7 + -7 = 0
0 + 3x = 4 + -7
3x = 4 + -7
Combine like terms: 4 + -7 = -3
3x = -3
Divide each side by '3'.
x = -1
Simplifying
x = -1
6% of $1,600 is = 96 if you multiple it with 180 : 96 × 180 = 17,280
Answer:
Step-by-step explanation:
Given Equation :
Using distribute property:
Adding the like terms we get :
Transposing the variables on the right side and constant terms on the left side :
Dividing both sides by 5 :
