Answer:
1) Expression
2) Equation
3) Equation
4) Expression
Step-by-step explanation:
An equation always contains an equal sign, so in this case, if it doesn't contain an equal sign, it's an expression.
For 2 and 3, you can see that there is an equal sign, but for 1 and 4, there is not.
Therefore, 1 and 4 are expressions and 2 and 3 are equations.
I hope this helped.
Answer:
Step-by-step explanation:
The answer is true because AB intersects with AC at point A
<span>2n^2 - 7n - 3 = 0
a = 2
b = -7
c =-3
Then use the Quadratic formula:
x = [-b +-sqroot(b^2 -4*a*c)] / 2*a
