The triangles in each pair are similar.
solve for x.

a) 10
b) 6
c) 8
d) 4

answer:

step-by-step explanation:

answer:

its a

step-by-step explanation:

the line marked   x + 8 corresponds to the line of length 3 ( in the smaller triangle).

as they are similar

6/36 = 3/(x + 8)

1 / 6 = 3 / (x + 8)

cross multiply: -

x + 8 = 18

x = 10

25.2

step-by-step explanation:

2+4x6-8/10= 25.2

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
