15y – 3(4y + 10)
-------------------------------
Distribute
= 15y + (-3) (4y) + (-3) (10)= 15y + -12y + -30
-----------------------------------------------
Combine the Like Terms
= 15y + -12y + -30= (15y + -12y) + (-30)= 3y + -30
----------------------------------------------------------
3y - 30 should be your answer

Hello!

Expression: 15y - 3(4y + 10)

The first step is to distribute.To do this we have to multiply the number that is before the brackets separately by all the number in the bracket.

15y + (-3)(4y) + (-3)(10)
15y + -12y + -30

Next we will combine like terms:

15y + -12y + -30= (15y + -12y) + (-30)
3y + -30

The terms we combined are: (15y + -12y)

Final answer: 3y - 30

Hope I helped you! (:

How do you this. Explain if you can so I can learn thx

Answer:

2 seconds

Step-by-step explanation:

Given

h = - 32t² + 64t

When the frisbee lands the height h = 0, that is

- 32t² + 64t = 0 ( multiply through by - 1 )

32t² - 64t = 0 ← factor out 32t from each term

32t(t - 2) = 0

Equate each factor to zero and solve for t

32t = 0 ⇒ t = 0

t - 2 = 0 ⇒ t = 2

t = 0 represents when the frisbee was thrown

and t = 2 when it lands

Hence it takes 2 seconds for the frisbee to land.

Find the derivative of g(y)=(y-4)*(2y+y^2)

sasho [114]

Answer:

$g'(y)=3y^2-4y-8$

Step-by-step explanation:

start by foiling out the given function

$g(y)=(y-4)(2y+y^2)\\=2y^2+y^3-8y-4y^2\\=y^3-2y^2-8y$

next, use the power rule to find the derivative

power rule: To use the power rule, multiply the variable's exponent n, by its coefficient a, then subtract 1 from the exponent. If there's no coefficient (the coefficient is 1), then the exponent will become the new coefficient.

$g'(y)=3y^2-4y-8$
