Pls help me i need it i will give brainliest help me pls ASAP

10. 0

11. -16

12. 2

13. 2

14. 3

15. 0

Step-by-step explanation:

10. (x+4)(x-4) --> x= 4, -4 --> 4 + (-4) = 0

11. 4(-4) = -16

12. 2(x-2)² --> x = 2

13. 2

14. x(x-3) --> x= 0, 3, 0+3=3

15. 0(3) = 0

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

(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
