Answer:
B) $17,704.05
Step-by-step explanation:
20 years later is a time in the future so you use Future value formula;
FV = PV* (1+r)^t
where PV= Amount invested in the present = $6,540
r= discount rate = (5% / 6) = 0.833% or 0.00833
t= total duration = 20 *6 = 120
Next, plug in the numbers into the formula;
=6,540* (1+0.00833)^120
=6,540 * 2.707041491
= 17,704.05
Answer:
a) Opposite sides are congruent and all interior angles are right angles, hence the quadrilateral <u>is</u> a rectangle
b) Opposite sides are parallel and all sides are congruent, hence the quadrilateral <u>is</u> a rhombus
c) All sides are congruent and all interior angles are right angles, hence the quadrilateral <u>is</u> a square
d) m∠AEB = 90° as the diagonals are perpendicular to each other
e) m∠EAD = 90°/2 = 45° as the diagonals of a square are bisectors of the angles at the vertices
12x=4(x+5) (multiplying 4 by each argument in the parenhesis)
12x=4x+20 /-4x both sides
8x=20 /:8 divide both sides by 8

15x-3(3x+4)=6 (-3 times each argument in the parenthesis)
15x-9x-12=6
6x-12=6 /+12 both sides
6x=18 /:6 divide both sides by 6
x=3
3x-5x+10=36
-2x+10=36 /-10 both sides
-2x=26 /:(-2) divide both sides by -2
x=-13
2(x+3)=x+10
2x+6=x+10 /-x
x+6=10 /-6
x=4
You have to divide the fractions by the numbers
