Answer:
lhs = (5+2√3)/(7+4√3)
= [(5+2√3)(7-4√3)]/[(7-4√3)(7+4√3)]
=[35-20√3+14√3-24]/[7²-(4√3)²]
=[11-6√3]/[49-48]
=11-6√3
therefore
11-6√3 = a+b√3
compare both sides
a= 11, b= -6
Step-by-step explanation:
Hope this answer helps you :)

2(x + 3) = 20
2x + 6 = 20
2x + 6 - 6 = 20 - 6
2x = 14
x = 7
Answer:
1/4
Step-by-step explanation:
y2-y1/x2-x1=m
6-5/9-5=1/4
Answer:
The correct option is C.
Step-by-step explanation:
The vertices of ABCD are A(2,-3), B(8,-6), C(14,-3), and D(8,0).
Distance formula:

The length of sides are




Since length of all sides are equation therefore the given parallelogram cannot be a rectangle.
Slope formula:

Slope of AB is

Slope of BC is

Since the slopes of two consecutive sides are not opposite reciprocals, therefore the given parallelogram is a rhombus. Option C is correct.
