Question

can you evaluate each expression and type the correct code? please remember to type in all caps with no spaces.
puzzle #1

a = 1 b = 2 c = 3
d = 4 e = 5 f = 0

1: evaluate
3b + a²

2: evaluate
4(e - c)

3: evaluate
2e - 3c

4: evaluate
e + a - 3f

answer choices
a: 0 b: 7 c: 4
d: 6 e: 3 f: 12
g: 5 h: 8 i: 1

type the 4-letter code into the answer box. all caps no spaces.

Explanation:

Step1: Evaluate \( 3b + a^2 \)

Given \( a = 1 \), \( b = 2 \). Substitute into the expression:
\( 3\times2 + 1^2 = 6 + 1 = 7 \). The answer choice with 7 is B.

Step2: Evaluate \( 4(e - c) \)

Given \( e = 5 \), \( c = 3 \). Substitute:
\( 4\times(5 - 3) = 4\times2 = 8 \). The answer choice with 8 is H.

Step3: Evaluate \( 2e - 3c \)

Given \( e = 5 \), \( c = 3 \). Substitute:
\( 2\times5 - 3\times3 = 10 - 9 = 1 \). The answer choice with 1 is I.

Step4: Evaluate \( e + a - 3f \)

Given \( e = 5 \), \( a = 1 \), \( f = 0 \). Substitute:
\( 5 + 1 - 3\times0 = 6 - 0 = 6 \). The answer choice with 6 is D.
