Question

Evaluate a(4b + c2) if a = 2, b = 5, and c = 1.

Answer 1

Answer:

The answer is 42 .

Step-by-step explanation:

Here,

a = 2

b = 5

c = 1

Now,

 $a(4b+c^{2} )$

$= 2(4 * 5 +1^{2} )$

= 2( 20 + 1 )

= 2 x 21

=42

Answer 2

Answer:

42

Step-by-step explanation:

a = 2, b = 5, and c = 1

• a*(4b + c²) =               ⇒ plug in values
• 2*(4*5 + 1²) =              ⇒ solving exponents
• 2*(20 + 1) =                 ⇒ parenthesis
• 2*21 =                         ⇒ multiplication
• 42                               ⇒ answer
