(2k² + 5k - 6)(3k - 1)
(6k³ - 2k² + 15k² - 5k - 18k + 6)
6k² + 13k² - 23k + 6

Use the FOIL method to simplify the problem.
(FOIL stands for first outer, inner, last)

Answer:

anglePUM = 3° , PM = 5, UM = √75

Step-by-step explanation:

anglePUM = 180 - 60 - 90 = 30° (∠sum of Δ)

cos60 = PM/10

PM = 10cos60 = 5

sin60 = UM/10

UM = 10sin60 = √75

bus a and bus b leave the bus depot at 4pm. Bus a takes 15 minutes to do its route and bus b takes 35 minutes to complete its ro
serious [3.7K]

Answer:

4.35pm is the later time, both buses were together back at the depot.

Reasons;

As bus b did not return his return route until 35 minute after departure.

We can say this was a return route taking 35 minute as the question does not point out length of time getting back. We therefore state it is a return route in the workings to explain how we found the answer.

Step-by-step explanation:

4.00 + 0.35 = 4.35 = b

4.00 + 0.15  = 4.15 = a

4.35 is the later time.

Graph: Y – 3=1/2(x +2)
tatuchka [14]

Answer:

Step-by-step explanation:y–3=½(x+2)

Multiply through by the denominator (2).

2×y–2×3=½(x+2)×2

2y–6=1(x+2) because the denominator (2) will cancel the other 2 multiplying it

2y–6=x+2

2y=x+2+6

2y=x+8
