Answer:
A = 14 mm²
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = 
bh ( b is the base and h the height )
Here b = 14 and h = 2 , then
A = × 14 × 2 = 7 × 2 = 14 mm²
Step-by-step explanation:
2x + 5x(5x-7) = 100
2x+ 25x-35x=100
2x -10x =100
-8x =100
x=2/25

Answer:
C=100+10x
Step-by-step explanation:
its 10$ per visit and x represents the number of visits. and you get a 1 time membership fee of 100 so its 100+10x=C c stand for cost.
For this case we must raise the equation according to the given statement.
Let the variable "x" be the unknown number.
So, three times the number is: 
If to that term is added "6" we have:
The sum of both terms is "12", then:
Thus, the equation is:
