Answer:

A=675cm²

Step-by-step explanation:

Area of triangle=1/2(base × height)

A=1/2(b × h)

A=1/2(6x × 9x)

where x=5

A=1/2(6×5×9×5)

A=1/2(30×45)

A=1/2(1350)

divide 1350 by 2

A=675cm²

The 21st, 37th and 56th term of an A.P. are consecutive terms of a G.P. Find the common ratio of the G.P.​
mash [69]

just use what you know about this stuff

(a+36d)/(a+20d) = (a+55d)/(a+36d)

(a+36d)^2 = (a+55d)(a+20d)

a^2+72ad+1296d^2 = a^2+75ad+1100d^2

3ad = 196d^2

3a = 196d

That is, for any value of n,

a=196n

d=3n

So, there is no unique solution.

If n=1, then a=196 and d=3. The terms are

196+20*3 = 256

196+36*3 = 304

196+55*3 = 361

304/256 = 361/304

You can easily verify that it works for any value of n.

How can i learn times faster like 3's til 12's in Times i have a hard time in my times can someone tell me how i can learn them
iogann1982 [59]
To get better at 12's:
Write down on your paper your 1's facts in column skip 5 and 11 going to 14 (a vertical line - line that goes up and down). To the right of that column, write your two's facts 0 to 8 and repeat again. Then you will have your 12's! Should look as follows

12's:

0    0 = 12 x0
1    2 = 12 x1
2    4 = 12 x2
3    6 = 12 x3
4    8 = 12 x4
6    0 = 12 x5
7    2 = 12 x6
8    4 = 12 x7
9    6 = 12 x8
10  8 = 12 x9
12  0 = 12 x10
13  2 = 12 x 11
14  4 = 12 x 12
