Answer:
answer: 9
Step-by-step explanation:
Assuming this is the Pythagorean theorem the formula is a²+ b² = c² so we arent given a but we are given c so we have to work backwards c = 15 and 15 × 15 = 225 12 × 12 = 144 225 - 144 = 81 so Now we just have to figure out what multiplied by itself equals 81 therefore 9 is our answer because 9 × 9 = 81 Hope that helps!

x =34.56°
Step-by-step explanation:
adjacent/ hypotenuse =cosx
cosx = 14/17
x = 
(14/17)
x =34.56°
Answer:
Answer is C
r= 3
there are 4 circles.
total area of circle = 4 π 3²
so shaded area = 12²- 4π3²= 30.90
Step-by-step explanation:
The system of equation that could have led to the equation 9x = 27 is
7x - 2y = 15
x + y = 6
The correct option is the third option
7x - 2y = 15
x + y = 6
<h3>Solving systems of equations</h3>
From the question, we are to determine the system that could have led to 9x = 27
1.
9x + 2y = 21
-9x - 2y = 21
Subtracting, we get
9x + 2y = 21
-9x - 2y = 21
-------------------
18x + 4y = 0
2.
10x - y = 15
x + y = - 12
Subtracting, we get
10x - y = 15
x + y = - 12
---------------------
9x -2y = 27
3.
7x - 2y = 15
x + y = 6
Here, multiply the second equation by 2
2 × [x + y = 6]
2x + 2y = 12
Now, add to the first equation
7x - 2y = 15
2x + 2y = 12
------------------
9x = 27
4.
4x + 3y = 24
-5x - 3y = 3
Subtracting, we get
4x + 3y = 24
-5x - 3y = 3
---------------------
9x + 6y = 21
Hence, the system of equation that could have led to the equation 9x = 27 is
7x - 2y = 15
x + y = 6
The correct option is the third option
7x - 2y = 15
x + y = 6
