Answer:

8.4 x 10^10= 84000000000 (because 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10)

3 x 10^7 = 30000000 (because 10 x 10 x 10 x 10 x 10 x 10 x 10)

I hope this helps and brainlest please !

Select the polynomial that is a perfect square trinomial.

cestrela7 [59]

The answer is <span>16x2 − 8x + 1
</span>
To be a perfect square trinomial, the rule must be used:
(a - b)² = a² - 2ab + b²

Let's check all choices
A. a = 7x, b = 4
(7x - 4)² = 49x² - 56x + 16

B. a = 2a, b = 5
(2a - 5)² = 4a² - 20a + 25

C. a = 5b, b = √10
(5b - √10)² = 25b² - 10√10 b + 10

D. a = 4x, b = 1
(4x - 1)² = 16x² - 8x + 1

A flower pot’s base has six sides that are all the same length. Each side measures x−6x-6 units. The base’s perimeter is 78 unit

NemiM [27]

Answer: The answer is x = 19.

Step-by-step explanation: Given that a flower pot has a base with six equal sides of measurement (x - 6) units. We are to find the value of the unknown quantity 'x' if the perimeter of the base is 78 units.

We know that the perimeter of a polygon is given by the sum of the lengths of all the sides of the polygon.

Since each side of the six-sided base is (x - 6) units, so its perimeter will be

$6\times(x-6)~\textup{units}.$

According to the question, we have

$6(x-6)=78\\\\\Rightarrow x-6=13\\\\\Rightarrow x=19.$

Thus, the value of 'x' is 19 units.
