Given f(x)=3x-5 and g(x)=2x+1, find g(f(x))

a)6x^2-7x-5
b)6x-10
c)6x-2
d)6x-9

*I thought it was a) but the answer comes out to be d) and i don't understand how or why they got this answer*

step-by-step explanation:

their are no angles. sorry cant .

i think asking google will you get the answer to that question

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
