What are the zeros of the quadratic function f(x) = 8x2 – 16x – 15?
x=-1-2 and x = -1 + 2
© x=--pand x = -1 +
© x=1- and x = 1 +
x = 1 - 77 and x = 1 + 77

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9

step-by-step explanation:

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
