\text {Area of the triangle } = \dfrac{1}{2} (6) (2) = 6

Area of 2 triangles = 6 x 2 = 12 units²

-

Area of the lateral surface = (3 + 3 + 6) x 7 = 84 units²

-

Total Surface Area = 12 + 84 = 96 units²

-

Answer: 96 units²

what is the least possible value of the smallest of 99 consecutive positive integers whose sum is a perfect cube
Dmitrij [34]
Let the least possible value of the smallest of 99 cosecutive integers be x and let the number whose cube is the sum be p, then

\frac{99}{2} (2x+98)=p^3 \\  \\ 99x+4,851=p^3\\ \\ \Rightarrow x=\frac{p^3-4,851}{99}

By substitution, we have that p=33 and x=314.

Therefore, <span>the least possible value of the smallest of 99 consecutive positive integers whose sum is a perfect cube is 314.</span>

What is six times six take away for plus nine<br><br><br>​
vladimir2022 [97]

Hello, thanks for using Brainly!

We are solving 6x6-4+9.

We will do three steps in this case.

First is 6x6, 6x6 is 30.

So now we must keep in our head we have 30 as our first number.

Now, let's -4 from 30. 30-4 is 26.

We just did step 2. Boom!

So, we have 26 as our second number. Let's do our third step.

If we have 26, we need to add 9 to that. To quickly find that we know that 26+10 is 36. That is adding ten, we need 9 so minus 1 from 36 we get 35.

Our final answer is 35.

the verticales of triangle XYZ are X(-3,-6),Y(21,-6),and Z(21,4). What is the perimeter of the triangle​
andrezito [222]

Answer:

<h2>P = 60</h2>

Step-by-step explanation:

The formula of a distance between two points:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

X(-3, -6), Y(21, -6). Substitute:

XY=\sqrt{21-(-3))^2+(-6-(-6))^2}=\sqrt{24^2+0^2}=\sqrt{24^2}=24

X(-3, -6), Z(21, 4). Substitute:

XZ=\sqrt{(21-(-3))^2+(4-(-6))^2}=\sqrt{24^2+10^2}=\sqrt{576+100}=\sqrt{676}=26

Y(21, -6), Z(21, 4). Substitute:

YZ=\sqrt{(21-21)^2+(4-(-6))^2}=\sqrt{0^2+10^2}=\sqrt{10^2}=10

The perimeter of the triangle XYZ:

P_{\triangle XYZ}=XY+XZ+YZ

Substitute:

P_{\triangle XYZ}=24+26+10=60
