Answer:

x = 9

Step-by-step explanation:

x² - 8x = 9

x² - 8x - 9 = 0

(x - 9)×(x + 1) = 0

x = 9 or x = -1

Positive solution : x = 9

Can someone help? I know the volume can someone help with the surface area?
TEA [102]
To find the surface area you will find the area of each flat surface or each face.


The faces are in the shape of a rectangle , so multiply the length by the width.

A = lw
Front/ Back-3 1/2 x 3 1/3 = 11 2/3 ft.²

Sides- 3 1/3 x 3 1/3 = 11 1/9 ft.²

Top/bottom - 3 1/2 x 3 1/3= 11 2/3 ft.²

Add together to get the total surface area.

11 1/9+11 1/9+11 2/3+11 2/3+11 2/3+11 2/3 = 68 8/9 ft.²

The total surface area is 68 8/9 ft.².

Reasoning triangle $abc$ has a perimeter of $12$ units. the vertices of the triangle are $a(x,\ 2),\ b(2,-2)$ , and $c(-1,\ 2)$
OlgaM077 [116]

hmmm let's find the distance between B and C first off.

~~~~~~~~~~~~\textit{distance between 2 points} \\\\ B(\stackrel{x_1}{2}~,~\stackrel{y_1}{-2})\qquad C(\stackrel{x_2}{-1}~,~\stackrel{y_2}{2})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ BC=\sqrt{(~~-1 - 2~~)^2 + (~~2 - (-2)~~)^2} \implies BC=\sqrt{(-1 -2)^2 + (2 +2)^2} \\\\\\ BC=\sqrt{( -3 )^2 + ( 4 )^2} \implies BC=\sqrt{ 9 + 16 } \implies BC=\sqrt{ 25 }\implies BC=5

hmmm if BC is that much, then AB + AC = 7, since AB + AC + BC = 12 which is the perimeter, Check the picture below.
