Answer:

29 m³

Step-by-step explanation:

The applicable formula is ...

V = (1/3)Bh

Assuming the height is 10 m, the volume is ...

V = (1/3)(8.7 m²)(10 m) = 29 m³

_____

The shape of the base is irrelevant.

Hi good morning can you please help me Write two polynomials whose difference is 6x+3

vaieri [72.5K]

Answer:

9x+8 and 3x+5.

Explanation:

Let the first polynomial = 9x + 8

Let the second polynomial be a+b

$\begin{gathered} 9x-a=6x \\ a=9x-6x \\ a=3x \end{gathered}$

Similarly:

$\begin{gathered} 8-b=3 \\ b=8-3 \\ b=5 \end{gathered}$

Thus, the second polynomial = 3x+5

Therefore, the two polynomials whose difference is 6x+3 are 9x+8 and 3x+5.

To find 5, Beau found 22 = 4 and 32 = 9. He said that since 5 is between 4 and 9, 5 is between 2 and 3. Beau thinks a good estim

Complete question

To find $\sqrt{5}$ , Beau found $2^2 = 4$ and $3^2 = 9$ . He said that since 5 is between 4 and 9, $\sqrt{5}$ , is between 2 and 3. Beau thinks a good estimate for $\sqrt{5}$ , is $\frac{2 + 3}{2} = 2.5$ Is his estimate high or low? How do you know?

Answer:

The estimation is high because 5 is very close to 4 so $\sqrt{5}$ will also be very close to $\sqrt{4}$ which is lower than the estimate

In order to get a good estimate

The first step is to choose a number between 2 and 3 let say 2.8 , 2,85 , 2.9 and the square them

i.e

$2.1^2 = 4.41$

$2.2^2 = 4.84$

$2.3^2 = 5.29$

From here we can see that $\sqrt{5}$ lies between 2.2 and 2.3 but is closer to 2.2

So a good estimate for $\sqrt{5}$ is 2.2

What are the simplified version of these?

Helga [31]

-2y-(-8y-2) = -2y + 8y + 2 = 6y + 2

2(3x + 16) - 7x = 6x + 32 - 7x = -1x + 32 = 32 - x

-x + 6 + (-3) + x + (-4) = -x + 6 - 3 + x - 4 = 3 - 4 = -1

Simplify thise expression 6ab + (–3x) + 2ab

Thepotemich [5.8K]

Simplify the following:

6 a b - 3 x + 2 a b

Grouping like terms, 6 a b - 3 x + 2 a b = -3 x + (6 a b + 2 a b):

-3 x + (6 a b + 2 a b)

a b 6 + a b 2 = 8 a b:

Answer: -3 x + 8 a b
