(a)
pavan saves = x
his 1st brother saves = x + 4
2nd brother saves = x +4
all together they save = x + x +4 + x + 4
= 3x+8
so
3x + 8 = 26
(b)
3x + 8 = 26
subtract 8 from.both side
3x + 8 - 8 = 26 - 8
3x = 18
divide by 3 both side
3x/3 = 18/3
x = 6
so pavan saves $ 6 each month

Answer:
Choice D
Step-by-step explanation:
38/4 =9.5
Therefore, this number is between 9 and 10
Note:
38/4 = 9 remainder 2
Hence, the quotient is 9 which is a whole number
(3x−2)(2x^2+5)
=(3x+−2)(2x^2+5)
=(3x)(2x^2)+(3x)(5)+(−2)(2x^2)+(−2)(5)
=6x^3+15x−4x^2−10
=6x^3−4x^2+15x−10
