Answer:

E. 64,000,000

Step-by-step explanation:

2^26 = (2^13)^2

But 2^13 = 8000 so

2^26 =  (8,000)^2

= 64,000,000

Jessii Vee is 1 5/8 gallons of paint to paint her room so he has 5/6 gallons of paint. How many more gallons of paint does she n
irakobra [83]

Answer:

3 1/2 gallons of paint

Step-by-step explanation:

1 5/8 - 5/6 = x

Turn the mixed number into an improper fraction:

1 5/8 = 13/8 = x

13/8 - 5/6 = x

make the denominator the same:

13/8 * 3 = 104/24

5/6 * 4 = 20/24

Subtract:

104/24 - 20/24 = 84/24

Simplify:

84/24 divided by 6 = 14/4

14/4 divided by 2 = 7/2

Turn into a mixed number:

3 1/2

The area of a rectangular garden is given by the trinomial x2 + x – 42. What are the possible dimensions of the rectangle? Use f
Murrr4er [49]

Answer:

Step-by-step explanation:

Hello, please consider the following.

x^2+x-42\\\\\text{The sum of the zeroes is -1=-7+6 and the product is -42=-7*6.}\\\\\text{So, we can factorise.}\\\\x^2+x-42\\\\=x^2+7x-6x-42\\\\=x(x+7)-6(x+7)\\\\=(x+7)(x-6)

So, the possible dimensions of the rectangle are (x+7) and (x-6).

Thank you.
