Answer:
x=9.89
Step-by-step explanation:
since both missing sides are equal, we give length x to both.
then, using the Pythagorean theorem, a²+b²=c², we get:
x²+x²=14²
we aolve for x:
2x²=14²
x²=14²/2
x=sqrt(14²/2)=9.89

Answer:
The solution of the equation 9x=7(x+2) is:
Option D) 7
Step-by-step explanation:
9x=7(x+2)
Eliminating the parentheses applying distributive property:
9x=7(x)+7(2)
Multiplying:
9x=7x+14
Grouping the x's on the left side of the equation: Subtracting 7x both sides of the equation:
9x-7x=7x+14-7x
Subtracting:
2x=14
Solving for x: Dividing both sides of the equation by 2:
2x/2=14/2
Dividing:
x=7
Solution: x=7 (option D)
