Answer:

f(x) = $x^{2}+5x+4$

Step-by-step explanation:

∵ The zeroes of the function are x = -4 and x = -1

∵ x + 4 = 0 and x + 1 = 0

∴ The factors of the function are (x + 4) (x + 1)

∴ The function = (x + 4) (x + 1)

∴ f(x) = $x^{2}+5x+4$

The height of a parallelogram is 6 feet more than its base. If the area of the parallelogram is 160 square feet, find the length

IRINA_888 [86]

Answer:

10 feet

Step-by-step explanation:

base= x feet

height=(6+x) feet

area= (6+x)x=160

=6x+x²=160 ==> x²+6x-160=0

factories the eqn obtained....

(x-10)(x+16)=0

x= 10 or -16

since length cannot be negative, x=10

since the base = x feet

base=10 feet

What is the slope of the line that passes through the points (5, 4) and (13.25, -18) ?

Murrr4er [49]

Answer:

Answer: D. 8/3

Step-by-step explanation:

Formular for slope:

[ consider points (x1, y1) and (x2, y2) ]

$slope = \frac{y_{2} - y _{1} }{x _{2} - x _{1} } \\$

x1 » 5, y1 » 4

x2 » 13.25, y2 » -18

$sloe = \frac{ - 18 - 4}{13.25 - 5} \\ \\ = \frac{22}{8.25} \\ \\ { \boxed{ \boxed{slope \: = \frac{8}{3} }}}$

g(x) = x^3 − x^2 − 4x + 4
g(x) = x^3 + 2x^2 − 25x − 50
g(x) = 2x^3 + 14x^2 − 2x − 14

Answer:

First and last one

Step-by-step explanation:

You have to use Pythagoras. Square the first two numbers (smallest) and then add them together. Square root the answer and if it gives you the largest number in the set, it‘s right

Hope this helps!
