Answer:
the numbers in parentheses are the values of X it wants you to plug in.
Step-by-step explanation:
for example: f(-6) = (-6)² - 3
f(2t) = (2t)² -3
Answer:
The constant of proportionality for this situation is 3.2
Step-by-step explanation:
For the given situation we can say that, the amount spent to fill the gas directly varies with the number of gallons of gas filled.
We can say,
where 
is the constant of proportionality which is nothing but the units rate of gas in dollars per gallon.
Dividing both sides by 22.5 to find
∴ 
Unit rate of gas = $3.2/gallon
∴ The constant of proportionality for this situation is 3.2.
Answer: A state has 11 electoral votes. In a presidential election, the Democratic candidate receives 48 percent of that state's popular vote, the Republican receives 40 percent of the vote, and an independent candidate receives 12 percent of the vote.

The lateral surface area consists of 2 sides with 11 unit long and 4 unit high, and 2 sides with 8 unit long and 4 unit high. Each side is a rectangle. So basically you use area of rectangle to determine the lateral surface area
lat sa = 2 × area of rectangle + 2 × area of rectangle
In this case, it will be
lat sa = (2 × l × h) + (2 × w × h)
lat sa = (2 × 11 × 4) + (2 × 8 × 4)
lat sa = 88 + 64
lat sa = 152
The lateral surface area is 152 squares unit
