Answer:

2y^2 -4y -24

Step-by-step explanation:

start by expanding the first term, also known as multiplying the 3

3(2y-8) to get 6y-24

then -2y and (5-y) to get -10y and 2y^2

(dont forget to include the negatives when mulitiplying it out)

then combine like terms to get

2y^2 - 4y - 24

Answer:

2( y^2 - 2y - 12).

Step-by-step explanation:

3(2y - 8) - 2y(5 - y)

Distribute the 3 and the -2y over the parentheses:

= 6y - 24 - 10y + 2y^2

= 2y^2 - 4y - 24

= 2( y^2 - 2y - 12).

First write both vectors in terms of their horizontal and vertical components.

G = (40.3 m)(cos(-35.0º) x + sin(-35.0º) y)

G = (33.0 x - 23.1 y) m

(where x and y are the unit vectors that point in the positive horizontal and vertical directions, respectively)

H = (63.3 m)(cos 270º x + sin 270º y)

H = (-63.3 y) m

Then the vector sum is

G + H = (33.0 x - 86.4 y) m

which has a magnitude of

|| G + H || = √[33.0^2 + (-86.4)^2] = 92.5 m

Rewrite the function W= 50+2.3(h-60) in order to express height as a function of weight
OLga [1]
You need to solve the equation for h.

<span>W= 50+2.3(h-60)

Distribute the 2.3.

W = 50 + 2.3h - 138

W = 2.3h - 88

Add 88 to both sides.

W + 88 = 2.3h

Switch sides.

2.3h = W + 88

Divide both sides by 2.3.

h = (W + 88)/2.3

A rectangular pan has a length that is 4/3 the width. The total area of the pan is 432 in.2. What is the width of the cake pan?
Maru [420]
<span>the width of the cake pan can be found with the following formula
area = W x L=</span>432 in.2<span>
but L= 4/3W
so we have </span>
area = W x 4/3W=4/3W²=<span>432 in.2, and </span><span>W²=<span>(3/4)x 432 in.2, and W=18 in</span> </span>
