Answer:
you cant solve for x but
55x/11x=5x
Step-by-step explanation:
Answer:
ΔABD ≅ ΔACD by SAS, therefore;
by CPCTC
Step-by-step explanation:
The two column proof is presented as follows;
Statement
Reason
ABCD is a trapezoid
Given
Given
Definition of a trapezoid
ABCD is an isosceles trapezoid
Left and right leg are equal
∠BAD ≅ ∠CDA
Base angle of an isosceles trapezoid are congruent
Reflexive property
ΔABD ≅ ΔACD
By SAS rule of congruency
CPCTC
CPCTC; Congruent Parts of Congruent Triangles are Congruent
SAS; Side Angle Side rule of congruency
I always prefer factoring, if there are simple factors.
There are simple factors here.
x² + 11x + 18 = 0
(x + 2) (x + 9) = 0
The left side is zero if either factor is zero.
First factor:
x + 2 = 0
<u>x = -2</u>
Second factor:
x + 9 = 0
<u>x = -9 </u>
Answer:
81b + 4 - 14/3b
Step-by-step explanation:
divide by 3b, u can leave the fraction in there
