Mathematics

Answer: C

<u>Step-by-step explanation:</u>

Replace x with -\frac{2}{3} and solve.

f(x) = 3x² - 6x - 1

f(-\frac{2}{3}) = 3(-\frac{2}{3})² - 6(-\frac{2}{3}) - 1

    = 3(\frac{4}{9}) + 4 - 1

    = \frac{4}{3} + 3

    = \frac{4}{3} + \frac{9}{3}

    = \frac{13}{3}

Infinite Algebra 2
Irina-Kira [14]
The first problem, all you need to do is combine like terms then isolate the n:
4n-2n=4
~subtract 2n from 4n (2n)
2n=4
~then divide both sides of the equation by 2 to isolate the n
n=4

The second problem follows the same steps of combining like terms and isolating the variable. Here, you'll have to combine 2 like terms:
-12=2+5v+2v
~first combine the variables which is just 5v+2v which is 7v
-12=2+7v
~then subtract 2 from both sides to isolate the 7v
-14=7v
~then divide both sides by 7 to isolate the v and get your answer
-2=v

Hope that helped!

pshichka [43]

Answer:

570

step-by-step explanation:

assuming you're talking about a 2-dimensional rectangle,

Area = base x height

base = 38

width = 15

Area = 38 * 15

Area = 570 ft

570ft * (1 yard/3ft) = 190 yards
