Hi there!
• x = - 3
Let's first calculate f(x) and g(x) individually :-
• f(x) = 4x - 7
⇒ 4(- 3) - 7
⇒ - 12 - 7 = - 19

• g(x) = 2x + 4
⇒ 2(- 3) + 4
⇒ - 6 + 4 = - 2

According to th' question :-
f(x) + g(x)
⇒ - 19 + (- 2)
⇒ - 19 - 2
⇒ - 21

~ Hope it helps!
1. None of the answer choices are correct, because the length that were to go with those numbers don't fit. The answer is D.
2. One coffee cost $4 and a latte would cost $2.50, because the other prices for a cup of coffee would exceed the price of the total of two coffees plus one latte and three coffees plus two lattes. The answer is A: $4.00.
3. This one has to be A, because you're finding how many nickels and dimes there are together if there are 24 coins. A nickel is 5 cents each and a dime is 10 cents each. The total of them combined is $1.85. The answer is A.
