Answer:

(3y + 2)(3y² + 4y - 2) = 9y³ + 18y² + 2y - 4.

Step-by-step explanation:

(3y + 2)(3y² + 4y - 2)

Break it up into two seperate equations.

(3y(3y² + 4y - 2)) + ((2)(3y² + 4y - 2))

Distribute the 3y into the equation.

(9y³ + 12y² - 6y) + ((2)(3y² + 4y - 2))

Distribute the 2 into the equation.

(9y³ + 12y² - 6y) + (6y² + 8y - 4)

Combine like terms.

9y³ + 12y² + 6y² - 6y + 8y - 4

9y³ + 18y² + 2y - 4.

A landscaping company has been commissioned to design a triangular flower bed for a mall

Deffense [45]

Answer:

A=b(1/2b-1)

112ft^2

Step-by-step explanation:

-Write the equation in factored form: A= b (1/2 b -1 )

-Supposed the base of the flower bed is 16 feet. What will the area be:

b=16 feet

Formula is A=1/2(1/2b-1)

Replace the b with 16

A=1/2 (16)^2 - 16

A=1/2 (256)-16

A=256/2 - 16

A=128-16

A=112 ft^2

The area will be 112 ft^2

The sum of 86, 68, and 38 is 192. What do you also know about the sum of 68, 38, and 86? Explain

trasher [3.6K]

It's the same because it's used the commutative property where:

a+b = b+a

So, 86+68+38=192 it's the same sum as 68+38+86=192
