How do you factor this trinomial 4a^2-4a+1

Mathematics
1 answer:
ElenaW [278]2 years ago
4 0

Answer:

(2a-1)(2a-1)

Step-by-step explanation:

To write the factored form, multiply a*c from the standard form ax^2+bx+c. Here it is 4*1 = 4.

Then find factors of 4 that add to b=-4.

4: 1,2,4

-2+-2 = -4

Split the middle term into -2x+-2x and factor by grouping.

4a^2-2a+-2a+1\\(4a^2-2a)+(-2a+1)\\2a(2a-1)-1(2a-1)\\(2a-1)(2a-1)

Notebooks cost $ 1.20 each. This weekend they will be on sale for $ 0.80. What percentage is the sale
Rainbow [258]

From the information we have, we know that each book costs 1.20 dollars. So we shall say this price is at 100% .

Now we need to form an equation to get the percentage  when the books are sold at 0.80 dollars.

100% = 1.20

       x = 0. 80

Where x is the new percentage when the sale is at 0.80 dollars.

We cross multiply the equation:

1.20 *x = 0.80 * 100

1.2x = 80

x = 80/1.2

x = 66.7%

Round off 66.7 to the nearest tenth we get 67%

The notebooks are sold at 67% (of the original cost).

Volume of a sphere with a diameter of 8 meters? Use 3.14 for pi.
kvasek [131]
Answer:   " 267.95 m³ " .
______________________________________________________
Explanation:
________________________________________________________


V = (4/3) * \pi * r³ ;

Given: diameter, "d" = "8 m" ;

radius, "r" = 8 m / 2 = 4 m " 
    
V = (4/3) * \pi * r³

V = (4/3) * \pi *(4m)³

V = (4/3) * (3.14) * 4³ * m³  ; 

V = (4/3) * (3.14) * (4*4*4) * m³ ;

V = (4/3) * (3.14) * (64) * m³ ;

V = 267.9466666666666667 m³ ;

round to: " 267.95 m³ " .
