Answer:
<em>2x^2 - 7x - 4</em>
Step-by-step explanation:
Given the expression f(x) = (2x+1)(x – 4)
To write it in standard form, we need to factorize it
(2x+1)(x – 4)
= 2x(x) - 2x(4) + x - 4
= 2x^2 - 8x + x - 4
= 2x^2 - 7x - 4
<em>hence the expression in standard form is 2x^2 - 7x - 4</em>
Answer:
B
Step-by-step explanation:
all sides are the same
This is the concept of trigonometry, to get the horizontal length we use the formula:
cos θ=(Adjacent)/(hypotenuse)
θ=6°
adjacent=x
hypotenuse=170m
thus the value of x will be:
x/170=cos6
hence:
x=170 cos 6
x=169.06872 meters
Answer: 169.06872 m
