Hey! :)

10y-3(y+5)

Distribute the -3. 

-3*y= -3y  -3*5= -15

10y-3y-15

7y-15

"A" is the answer.

sergejj [24]

Answer:

Width = 8 feet

Length = 8 feet

Step-by-step explanation:

Carlos is extending hood backyard patio. Currently, the area of the patio is n²-16n+64.

Step

We find the Length and Width

This is done by factorising the area

Area = n² - 16n + 64 = 0

n² - 8n - 8n + 64 = 0

(n² - 8n)  - (8n +64) = 0

n(n - 8)  -8(n - 8) = 0

(n - 8) (n - 8) = 0

n - 8 = 0

n = 8

The length and width  = 8 feet

Step 2

New length and width by extension is calculated as:

Width = 8 feet + 2 feet = 10 feet

Length =  8 feet + 2 feet = 10 feet

A box is to be constructed with a rectangular base and a height of 5 cm. If the rectangular base must have a perimeter of 28 cm,
Irina18 [472]

Answer:

V = (5)(14 L - L^2) cm^3

Step-by-step explanation:

Let the dimensions of the rectangular base be W by L and the height be H.

The perimeter must be 28 cm, so 28 cm = 2(W) + 2(L).  This reduces to

14 cm = W + L, which can be solved for either W or L.  Solving for W:  

W = 14 cm - L

Then the area of the rectangular base is A = W*L, or A = (14 cm - L)(L), or

A = 14L - L^2.

The volume of the box is then V = A*H.  

Because H = 5 cm, the volume is V = (5 cm)A, or

                                                        V = (5 cm)(14L - L^2) cm^2

This is a quadratic equation.  Putting it into standard form yields:

V = (5)(14 L - L^2) cm^3.  This is the desired quadratic formula.
