<span>2x − 3y − z
</span><span> x = −2,
</span><span> y = 3,
</span><span> z = −2
What we must do is replace the values given in the equation. We have then replacing:
</span> 2*(-2) - 3*(3) - (-2) = -11
The answer is -11
Answer:
A = 3.14 yd^2
Step-by-step explanation:
The circumference is given by
C = 2 * pi * r
Letting pi be approximated by 3.14
6.28 = 2 * (3.14) *r
6.28 = 6.28 r
Divide each side by 6.28
6.28/6.28 = 6.28r/6.28
1=r
We can find the area by
A = pi r^2
A = 3.14 (1)^2
A = 3.14
Answer:
The solution is x =2 for the given equation 
Step-by-step explanation:
We need to find the solution for x in the given equation.

Solving:
Subtract
from both sides

Taking square on both sides

Putting values and solving

Verifying the solution by putting values of x in given equation
Putting x=18

So, x=18 is not solution o given equation.
Putting x = 2

So, x=2 satisfies the equation
The solution is x =2 for the given equation 
Finding the factors of a number involves both prime and composite numbers while finding the prime factors of a number involves only prime numbers.
