Which of the following is a factor of 2xy + 8y − 8x − 32?

melamori03 [73]

We are given

$2xy+8y-8x-32$

We can write it as

$=2y*x+2y*4-8*x-8*4$

we can see that 2y is in first two terms

and -8 is in last two terms

so, we can factor it out

$=2y(x+4)-8(x+4)$

now, we can see that x+4 is common in both terms

so, we can factor it out

$=(x+4)(2y-8)$

we can see that

x+4 is one of factor of terms

so, option-B..........Answer

For this problem what I did was that I multiplied 100 x 34 = 3,400 and subtracted that answer with 5,086. The answer I got was 1

inessss [21]

Answer:

The answer rounded to the nearest whole number is 1729

Step-by-step explanation:

Set it up like this: Percent in fraction form = x over total

So: 34/100 = x/5086

You then multiply: 34 x 5086 = 172924

Then divided that number by 100: 172924 divided by 100 = 1729.24

Then round the number to the nearest whole number: 1729

Hope this helps good luck!

Simplify (ignore my garbage camera quality ....)

monitta

Answer:

C. 3

Step-by-step explanation:

Given expression is:

$({3^{\frac{1}{7}})^7$

We know that the rules of exponents are used to solve these kind of questions.

When there is exponent on exponent like in this question 1/7 has an exponent of 7 , the exponents are multiplied.

So,

$=3^{(7*\frac{1}{7} )}$

The 7's will be cancelled out and remaining power will be 1

$=3^1\\=3$

Hence, option C is correct ..
