Answer:

6y^2+2y

Step by step explanation:

2y*(y+3)+4y*(y-1)

Distribute 2y through the parentheses

2y^2+6y+4y*(y-1)

Distribute 4y through the parentheses

2y^2+6y+4y^2-4y

Collect like terms

6y^2+6y-4y

Collect like terms

6y^2+2y

Answer

6y^2+2y

Answer:

6y² + 2y

Step-by-step explanation:

Use distributive property:a*(b+c) =a*b + a*c

2y(y + 3) + 4y(y -1) =2y*y + 2y*3 + 4y*y - 4y*1

                             = 2y² + 6y + 4y² - 4y

                             = 2y² + 4y² + 6y - 4y      {Combine like terms}

                             = 6y² + 2y

Please help find them <br>1 AB<br><br>2 BC​
spin [16.1K]

Answer:

AB ≈ 15.7 cm, BC ≈ 18.7 cm

Step-by-step explanation:

(1)

Using the Cosine rule in Δ ABD

AB² = 12.4² + 16.5² - (2 × 12.4 × 16.5 × cos64° )

       = 153.76 + 272.25 - (409.2 cos64° )

       = 426.01 - 179.38

       = 246.63 ( take the square root of both sides )

AB = \sqrt{246.63} ≈ 15.7 cm ( to 1 dec. place )

(2)

Calculate ∠ BCD in Δ BCD

∠ BCD = 180° - (53 +  95)° ← angle sum in triangle

∠ BCD = 180° - 148° = 32°

Using the Sine rule in Δ BCD

\frac{BC}{sin53} = \frac{BD}{sin32} = \frac{12.4}{sin32} ( cross- multiply )

BC × sin32° = 12.4 × sin53° ( divide both sides by sin32° )

BC = \frac{12.4sin53}{sin32} ≈ 18.7 cm ( to 1 dec. place )

cluponka [151]
Do you remember when you were learning about the "Least Common
Multiple" of two numbers, and you were wondering why you had to learn
it, because you were so sure that you'd never need to use it ?  Do you
remember that ?

Well, HERE's where you get to use it.  This question is just looking for
the LCM of 6 and 15 .  THAT's how many days it will be before you get
homework in both subjects on the same day again.

(It's not 90 days, and it's not 60 days.)
