Answer all. 100 points + brainliest

Step-by-step explanation:

#1

a) 5

b) 2x and 6x,

c) 3x^2+8x+23

d) Factors of 7, 1 and 7, -1 and -7

#2= the second third and fifth

#3

5a^2+6a-3

#4 P=w(2)+5

#5 9x-2y+4z,   3c^2+5c-6,   n^3+17m-15p

#6: -8r^2t^2-9rt^2-2rt-15,   4,   4,    -8r^2t^2,    -15

hope this helps. (when a number has ^2 that means squared)

my answer came out just like the other user

1)

a) 5

b) 2x and 6x,

c) 3x^2+8x+23

d) Factors of 7, 1 and 7, -1 and -7

2)= the second third and fifth

3)

5)a^2+6a-3

4) P=w(2)+5

5) 9x-2y+4z,   3c^2+5c-6,   n^3+17m-15p

6): -8r^2t^2-9rt^2-2rt-15,   4,   4,    -8r^2t^2,    -15

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
