Can someone help me on this ?

1.) A=Bh-Bh=First Image

2.)A=Bh- πr^2=3rd Image

3.)A=BH + BH/2= Bottom image

4.)A=bh+ bh/2 + πr^2/2= 2nd image

Step-by-step explanation:

Hope this helps! :)

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

first, let's see what the pattern is.

58 - x = 47

46 - x = 36

x = 9

so this means that the term after 25 is 25 - 9:

the next term in the sequence is 16.
