Evaluate 7 3 4 + ( − 2 1 5 ) x for x = − 10 .
a. − 55 1 2 b.-14 1/4 c. 29 3 4 d. 99 1 2

2884

Step-by-step explanation:

Evaluate 7 3 4 + ( − 2 1 5 ) x for x = − 10 .

734 + (-215)x when x = -10

+ × - = - (plus times minus = minus)

Therefore,

734 - 215x

x = -10

so replace x in the equation with -10

734 - 215 × -10

- × - = + (minus times minus = plus)

734 + 2150 =

2884

The options have no correct answer

answer: idk

step-by-step explanation:

(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
