4.b.
Answer: See below.
Step-by-step explanation:
<h2><u>
For the equation f(x) = 2x</u></h2>
3.a. f(6) means use x = 6 in the equation f(x) = 2x
so f(6) would be f(6)= 2(6)
<u>f(6) = 12</u>
3.b. f(-11) = 2(-11)
<u>f(-11) = -22</u>
3.c. f(2.75) = 2(2.75)
<u>f(2.75) = 5.5</u>
3.d. This is turned around. We are told f(x)=20, so what would x need to be for f(x) to be 20? Since f(x) = 2x, we can say 20 = 2x. Therefore x = 10
f(10) = 20
<u>The rest of (3) are solved in the same fasion.h</u>
<u></u>
<h2><u>
For the equation f(x)= 5x+50</u></h2>
4.a. f(7) = 5(7)+50
<u>f(7) = 85</u>
4.b. f(-12)
f(-12) = 5*(-12)+50
<u>f(-12) = -60</u>
<u></u>
Continue in the same fashion for these types of problems.
Integers between -4 and 0 are : -3, -2, and -1
Answer:
The answer to your question is SA = 2419.34 m²
Step-by-step explanation:
Data
a = 11.42 m
side = 11 m
height = 20 m
Formula
SA = 2B + PH
Process
1.- Calculate P
Perimeter = P
P = 7(11)
= 77 m
2.- Calculate B
B = Pa/2
= (77)(11.42)/2
= 879.34/2
= 439.67 m²
3.- Calculate 2B
2B = 2(439.67)
= 879.34 m²
4.- Calculate PH
PH = (77)(20)
= 1540 m²
5.- Calculate SA
SA = 879.34 + 1540
= 2419.34 m²
26 is c
Step-by-step explanation:

cannot be changed to a mixed number. 10 could divide both numerator and denominator. And you get 2.
