The first inequality given is:
5x - 11 < -11
5x < -11 + 11
5x < 0
x < 0
This means that : x ∈ ]-∞,0[
The second inequality given is:
<span>4x + 2 > 14
</span>4x > 14-2
4x > 12
x > 3
This means that:
x ∈ ]3,∞[
Since the two inequalities are linked by an "or", this means that the solution is the union of the two intervals:
x ∈ ]-∞,0[ U ]3,∞[
The 2 interior angles add to the exterior angle
26+13=x
39=x
x=39°
because
remember, all angles add to 180
26+13+BCA=180
39+BCA=180
minus 39 both sides
BCA=141
look, we want x
BC is a striaign line which is 180
BCA+x=180
141+x=180
minus 141 from both sides
x=39°
Answer:
-z( 2z^3-5z^2+9z-1)
Step-by-step explanation:
Apply exponent rule: a^b+c=a^b*a^c
z^2=zz
z^3=z^2*z
z^4=z^3*z
Factor out common term z:
-z(2z^3-5z^2+9z-1)
a square is a quadrilateral
