12. the product 6x4 can be found by thinking of the problem
as 6(10 + 4) = 6x10 + 6x4 = 60 + 24 = 84.
a. what properties are being used?
b. use this technique to mentally compute 32x12.

v: l•w•h÷2.

v: 20•6•8 ÷2

v: 960÷2

v: 480

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,

step-by-step explanation:

a and d

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
