F(x)=3x2-15x-42 f(x)=5x2+50x+125
needs to be answered like this
f(x)=3(???)(???)
algebra

3(−7)(+2)

5(+5)²

Step-by-step explanation:

f() = 3² - 15 - 42 = 3(−7)(+2)

f() = 5² + 50 + 125 =  5(+5)²

That is how you factor them. Hope this helps :)

step-by-step explanation:

3024 rhe base is what up in worry about

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
