Answer:
x=12
Step-by-step explanation:
32=2(4+x)
distribute 2.
32=8+2x
subtract 8 from both sides.
32=8+2x
-8 -8
24=2x
divide by 2 on both sides
24/2=2x/2
12=x
Answer:
bottom: 12 x 12 = 144
1st triangle: (12 x 8)/2 = 48
2nd triangle: 48
3rd triangle: 48
4th triangle: 48
144 + 48 + 48 + 48 + 48 = <u>336 cm squared</u>

Answer:
$11654 approx
Step-by-step explanation:
Given data
Principal amount = 22300 dollars
Rate= 10.25%
time= 6 years
The expression for the decrease is given as
A=P(1-r)^t-----------Note the negative sign is because of the decrease
substitute
A= 22300(1-0.1025)^6
A=22300(0.8975)^6
A=22300*0.5226
A=$11653.98
Hence the new value is $11654 approx
<span>22% of $40 is $8.80 so the now rate should be $40.00+$8.80=$48.80</span>
