Answer:
a.) Vertical Angles
b.) Given (Parallel)
c.) Substitution
Step-by-step explanation:
Answer:
Prime
Step-by-step explanation:
x² + 20x − 36
You must find a pair of numbers that multiply to give -36 and add to give +20.
The likely candidates are 2 and 18, and they must have opposite signs to give a negative product.
+2 × (-18) = -36; +2 + (-18) = -16
-2 × 18 = -36; -2 + 8 = +16
Neither combination gives +20 as the sum.
The expression can't be factored with rational numbers.
The expression is prime.
For this case we have to by definition:
1 kilojoule equals 0.239006 kilocalorie.
1 kilocalorie equals 1000 calories
Then, if we have:
Now:
Answer:
Answer:
x= y+2/3+4
Step-by-step explanation:
For you to make an equation a quadratic equation, you need everything to be on one side, so you add one to both sides.
