Since the sides are not equal in length. The triangle are not congruent
Answer:
K(A+B)/A
Step-by-step explanation:
K = (AB)/(A+B)
K(A+B)=AB
K(A+B)/A=B
Set 7x-4 and 31 equal to each other
7X-4=31
Add four to both sides
7X=27
X=3
The answer is D
$50000 + (9%x(10000x$20)=
$50000 + (9%x$200000)=
$50000 + $18000=
$68000
