Question

1. evaluate the expression for s = 3, t=-4, and u = 17. plug in desmos write out exactly what you would type into desmos 2st + u = 6. simplify the expression: combine like terms 5f+10f + 2f+10f 7. combine any like terms in the expression. if there are no like terms, rewrite the expression. 6d + 4d 8. write an expression for the sequence of operations described below. triple the difference of p and 6 do not simplify any part of the expression.

Explanation:

Step1: Substitute values in 2st + u

Given s = 3, t=-4, u = 17. Substitute into 2st+u:
$2\times3\times(-4)+17$

Step2: Calculate multiplication first

$2\times3\times(-4)=6\times(-4)= - 24$
So the expression becomes -24 + 17

Step3: Calculate addition

$-24+17=-7$

Step4: Combine like - terms in 5r + 10r+2r + 10r

$(5 + 10+2 + 10)r=27r$

Step5: Combine like - terms in 6d + 4d

$(6 + 4)d = 10d$

Step6: Write the expression for triple the difference of p and 6

The difference of p and 6 is p - 6. Triple it gives 3(p - 6)

Answer:

1. -7
2. 27r
3. 10d
4. 3(p - 6)
