Answer:
4a (n-1) + 5
Step-by-step explanation:
1th=6
2nd=29
3rd=121
4th=489
.
.
nth
if n=2
a2 = 4a(2-1) + 5 = 4 a(1) + 5 = 4 (6) + 5= 29
a3 =4a(3-1) + 5 = 4 a(2) + 5 = 4 (29) + 5= 121
try finding a4, check wether the answer is 489
I hope this helps you
1000 ml=1 lt
2300 ml=? lt
?=2300/1000
?=2,3 lt
The answer is (0,6) because you go 3 left and 2 up making that the new point
Answer:
Step-by-step explanation:
I think you're supposed to add all of the sides together and then you get your area.
<span>Let x be length of shorter leg
</span>4cm longer than the shorter leg<span> x + 4 = length of longer leg
</span>hypotenuse is 8 cm longer than the shorter <span>
x + 8 = </span>length of <span> hypotenuse
</span>
phytagorus rule
<span>x^2 + (x+4)^2 = (x+8)^2
x^2 + x^2 +8 x + 4^2 = x^2 + 16x + 8^2
x^2 - 8x - 48 =0
(x + 4 ) (x - 12) - 0
x= - 4 we reject negative number
so x= 12
