Which of these is the algebraic expression for the verbal expression "twelve times the difference of a number and four? "   a.12 ⋅ x − 4 b. x − 4 ⋅ 12   c.4(x − 12)   d.12(x − 4)

d. 12(x - 4)

Step-by-step explanation:

"the difference of a number and four" is represented as (x - 4), and now we have to multiply that expression by 12 to get:

12(x - 4).

With these expressions that need to be translated into words, oftentimes we are required to start at the end of the expression and work backwards to the beginning.  I read through the sentence and realized that "the difference between a number and four" was my main expression, and then working backwards to the beginning, I see that I am multiplying that main expression by 12.  Keep that in mind.  A lot of times, this is the way to read these.

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

£56

step-by-step explanation:

u divide 24 by 3 and u get 8 so if u do 8 time 7 or 8+8+8+8+8+8+8 u get 56 and 56 divided by 7 is 8.
