Answer:
since a,7,b,23,c are in A.P.
first term t1=a
second term t2=7
common difference (d)=7-a
forth term t4=a+3d
23=a+3(7-a)
23=a+21-3a
23=21-2a
2a=21-23
a=-2/2=-1
common difference =7-a=7--1=8
third term =a+2d=-1+2×8=15
:.b=15
5th term =c
a+4d=c
c=-1+4×8=31
a=-1
b=15
c=31
Answer:
two mulplied by x plus seven
Step-by-step explanation:
2x is 2 mulplied by x and then + 7 is plus seven put it all together and you get 2 mulplied by x plus seven
does that
make sense?
The answer is 4,615.8 cubic centimeters
The volume of a cylinder is pi*radius^2*height
If pi is 3.14 and you plug in the radius (7cm) and the height (30cm), you get 3.14*7^2*30, which equals 4,615.8 cm cubed
$2.41/3=.80 The original answer was .803 repeating 3. But you round
