which expression is equivalent to 3(4 - 8) - 2 x 6^2?

a. 3(4) - 2 x 36

b. 3(4) - 2 x 12

c. 3(-4) - 2 x 36

d. 3(-4) - 2 x 12

C. 3(-4) - 2 × 36

Step-by-step explanation:

The question 3(4-8) - 2 × 6^2 requires the use of BIDMAS

Rule.

First, solve the problem in the brackets thus:

3(-4) - 2 × 6^2

Then solve the problem in index form which is 6^2. Note that 6^2 implies 6 × 6 = 36. Thus:

3(-4) - 2 × 36

Therefore, the equivalent expression of 3(4-8) - 2 × 6^2 is

3(-4) - 2 × 36

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,
