Answer:
1233cm^2
Step-by-step explanation:
a of triangle = 1/2 bh
1/2 x 12 x 9 = 54
108 x 2 = 108
a of regtangle = l x w
25 x 15 = 375
375 x 3 = 1125
total surface area = 1125 + 108 = 1233cm^2
Considering the above Arithmetic sequence, we can conclude that each term in the sequence is in the form of [ 3+2n ] where, n ≥ 0.
So, Correct option is A
~ a(n)=3+2n for n≥0 ~

Answer:
22 in.
Step-by-step explanation:
total volume= big thingy + long thingy
=>x=2.2.3+5.2=12+10=22
25-4^2/8=
4^2= 16
16/8= 2
25-2=23
The answer to the first question is 23.
12*5-8/4+7*2=
12*5= 60
8/4= 2
7*2= 14
60-2+14= 72
The answer to the second question is 72.
Number one is 23.
Number two is 72.
