Factor the following:
x^8 - 1/84

Put each term in x^8 - 1/84 over the common denominator 84: x^8 - 1/84 = (84 x^8)/84 - 1/84:
(84 x^8)/84 - 1/84

(84 x^8)/84 - 1/84 = (84 x^8 - 1)/84:
Answer:  (84 x^8 - 1)/84

Determine the value of a + b in the system of equations below. <br><br> 5a + 4b = 22<br> 7a-b= 11
dexar [7]

Answer:

We have a + b as;

2 + 3 = 5

Step-by-step explanation:

Here, we want go get the value of a and b

from the second equation, we can get an expression for b

We have this as;

7a - b = 11

Thus,

b = 7a - 11

Now, from here, we can substitute the value of b into the first equation

We have this as;

5a + 4(7a - 11) = 22

5a + 28a -44 = 22

33a = 22 + 44

33a = 66

a = 66/33

a = 2

Recall;

b = 7a - 11

substituting the value of a from above;

b = 7(2) - 11

b = 14 - 11

b = 3

Can someone Plzzz help me out???

Hello from MrBillDoesMath!


Answer:  3


Discussion:

The perimeter of a polygon is the sum of the side lengths.

Perimeter of top polygon is   (x+2) + 2x + (x + 2) + (4x + 1) =  8x + 5

Perimeter of bottom triangle is   4x + 2x + (3x+2 ) =  9x + 2


The perimeters are the same when

8x + 5 = 9x + 2

Subtract 8x from both sides:

5 = (9x - 8x) + 2   or

5 = x + 2

Subtract 2 from each side to get x = 3:

5 -2 = 3 = x


The perimeter of either figure is 29
