Answer:
( 8 , - 8) => x² - 55 = 9
( 4 , - 4) => 2x² - 32 = 0
(5 , - 5) => 4x² - 100 = 0
(11 , - 11) => x² - 140 = -19
( 3, - 3) => 2x² - 18 = 0
Step-by-step explanation:
1)

x = ( 4 , - 4)
2)

x = ( 5 , - 5 )
3)

x= ( 8 , - 8)
4)

x = ( 11 , -11)
5)

x = ( 3 , - 3)
36 and 48
a = b+12
a+b = 84
(b+12) + b =84
2b +12 = 84
2b = 72
b= 36
a = b + 12
a = 36 + 12
a = 48
Answer: Yes. (gof)(0) = -5
(gof)(0) means you will find the function of g(f(0)), which means we will find f(0) and plug that value in for x in the function g(x)
We know f(0) is -1, so we can plug -1 into the equation of g(x)
(gof)(0) = (-1) - 4
(gof)(0) = -5
Answer:

Step-by-step explanation:
V= <em>lwh</em><em> </em>or <em>l</em><em> </em><em>*</em><em>w</em><em>*</em><em>h</em>
<em>Length</em><em>:</em><em> </em><em>15</em>
<em>Width</em><em>:</em><em> </em><em>3</em>
<em>Height</em><em>:</em><em>4</em>
<em>V</em><em>=</em><em>15</em><em>*</em><em>3</em><em>*</em><em>4</em>
V=180
