6 The length of the side of a square is (x + 6).
Brums [2.3K]

Answer:

x^2 ×1 2x + 36

Step-by-step explanation:

area of a square = L × B

= (x+6) (x+6) since a square has 4 equal sides, it becomes (x+6) (x+6)

= x(x+6) +6(x+6)

= x^2 + 6x + 6x +36

= x^2 + 12x +36 added all the like terms 6x + 6x = 12x

hope this helps ☆☆☆

Determine a polynomial that represents the area of the parallelogram.<br> A=
sp2606 [1]

Answer:

4b² - 16

Step-by-step explanation:

The formula to find the area of a parallelogram equals bh, where b = base and h - height. We're given the base as 2b + 4 and the height as 2b - 4.

  • (2b+4)*(2b-4)=(2b+4)(2b-4)
  • (2b+4)(2b-4)=(2b)(2b)+(2b)(-4)+(4)(2b)+(4)(-4)
  • 4b^2-8b+8b-16
  • 4b^2-16

Therefore, the answer is 4b² - 16.

What's the difference between two whole number 1/2 percent of 36 and 30% of 10<br>​
AlexFokin [52]

Here, we proceed step by step, to obtain our answer,

\frac{1}{2}  % of 36 can be written as ,

0.5 % of 36 , which means,

100 % refers to 36, then

0.5 % refers to what,  thus, by cross multiplication we get,

0.5 % of 36 =  \frac{0.5 X 36}{100} = 0.18 ___(1), which can be expressed in whole numbers as 0.

Now, 30 % of 10 means,

100 % refers to 10, then

30 % refers to what,  thus, by cross multiplication we get,

30 % of 10 = \frac{30 X 10}{100} = 3 __(2)

From equations (1)  and (2),

the whole numbers that we obtain are 0 and 3, respectively,

Thus the difference between these two whole numbers is,

= 3 - 0 = 3.
