Question

Evaluate B2 for B = 9.
and this one. Not really good a math but this site has helped me out a lot
Evaluate ab + c for a = 2, b = 3, and c = 4.

Answer 1

B2....b = 9
9(2) = 18.....unless that 2 is ^2...in that case B^2 = 9^2 = 81

ab + c.....a = 2, b = 3, c = 4
(2)(3) + 4 = 
6 + 4 = 
10

Answer 2

Answer:

1. The value of B² is 81.

2. The value of ab+c is 10.

Step-by-step explanation:

1.

We need to find the value of B².

The given information is

$B=9$

Taking square on both the sides.

$B^2=9^2$

$B^2=81$

Therefore the value of B² is 81.

2.

Given information: a = 2, b = 3, and c = 4.

We need to find the value of ab+c.

Substitute a = 2, b = 3, and c = 4 in ab+c, to find the value of ab+c.

$ab+c=2(3)+4$

$ab+c=6+4$

$ab+c=10$

Therefore the value of ab+c is 10.
