Factor the given polynomial 4a^2 + 18ab − 10b^2.

Select one:
a. ( 6a − 2b )( 3a + b )
b. ( 5a − b )( 2a + b )
c. ( 3a − 1b )( 2a + 5b )
d. ( 4a − 2b )( a + 5b )

step-by-step explanation:

circumference divided by 3.141592654 then timesthe radius twice

(a) common ratio in the given sequence is, 3

(b) push ups will do kendall do on the 20th week

step-by-step explanation:

geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio(r)

(a)

given the sequence: 6 , 18 , 54 , 162 ,

this sequence is geometric sequence where each term is 3 times the previous term.

therefore,

common ratio(r) = 3.

(b)

a formula for nth term of geometric sequence is given by;

,   where r is the common ratio between the successive terms and is the first term,

to find how many push ups will kendall do on the 20th week.

here. n = 20th term.

in the given sequence first term

then;

simplify:

therefore, push ups will do kendall do on the 20th week
