Answer:

i) Zero product property

ii) Square root property

Step-by-step explanation:

(x + 4)(x -9) = 0

Here we are equating each factor equal to zero and find the solutions.

Therefore it is Zero product property.

4x^2 = 20

To find the value of x, we take the square root on both sides.

So it is square root property.

Hope this will helpful.

Thank you.

Leno4ka [110]

Answer:

last one

Step-by-step explanation:

x = width

x+6 = length

Area = length times width

x(x + 6) = x^{2} + 6x

x^{2} + 6<em>x = 114   (subtract 114 from both sides) </em>

10. How many three-topping pizzas can be ordered from the list of toppings below? Did you calculate the number of permutations o
Nimfa-mama [501]

Step-by-step explanation:

Total numbers of pizza toppings = 12

Number of three topping pizzas can be ordered are:

P^{n}_{k}=\frac{n!}{(n-k)!}

where = n = number of elements

k = number of elements choosen

n= 12 , k = 3

\frac{12!}{(12-3)!} =\frac{12\times 11\times 10\times 9!}{9!}= 1,320

We calculated the number of permutations. We made this choice because in permutation order of element matters but in combination its not.
