Answer:
3x^2+3x+2
This is not factorable with rational numbers.
Answer:
x = -2
y = -4
Step-by-step explanation:
The way systems of equations work is that you have to substitute to solve for a variable *(only one of the 2 ways to figure this out)*
so, we will use addition property of equality in a form to add the two equations together, since +5y and -5y added together will cancel out.
that would leave
5x = -10
divide both sides by 5
x = -2
Now that we know x = -2, we can plug in -2 into one of the equations to find y.
2 ( -2) + 5y = -24
-4 + 5y = -24
-4 + 4 + 5y = -24 + 4
5y = -20
y = -4
x = -2
y = -4
The pattern
5 10 3 15 20 13 25 30....
the next number is
23 because after each 2 numbers its +10

True

Step-by-step explanation:</h2>
A counterexample is a special type of example that is an exception to a general rule, law, proposition or statement. Hence if we prove that then this is a counterexample for the expression . Thus:
So we observe that the equation is not fulfilled because . In conclusion:
<u><em>A counterexample for the expression sin(x)+cos(x)=1 is 45° </em></u><u><em>is true!</em></u>
