How do i find the surface area?

daser333 [38]

Surface area is what it seems to be. All of the area of the solid's faces together. Like a cube, just find the areas of all of the squares that make the cube then add them together.

- 8/9x - 4/45x + 1/5x = - 70

lara31 [8.8K]

Answer:

x = 90

Step-by-step explanation:

- $\frac{8}{9}$ x - $\frac{4}{45}$ x + $\frac{1}{5}$ x = - 70

Multiply through by 45 ( the LCM of 9, 45, 5 ) to clear the fractions

- 40x - 4x + 9x = - 3150 , that is

- 35x = - 3150 ( divide both sides by - 35 )

x = 90

X ^ 2 + 4x - 7 = 0<br><br> Solve using the Quadratic Formula

aalyn [17]

There's a special case of the quadratic formula called the Shakespeare Quadratic Formula (2b or -2b) that applies when the linear coefficient is even.

$x^2-2Bx + C \textrm{ has zeros }x = B \pm\sqrt{B^2 - C}$

If you're planning on solving a lot of quadratic equations quickly, it's good to know.

Here we have

$x^2 + 4x - 7 = 0$

$x = -2 \pm \sqrt{2^2 - -7}$

$x = -2 \pm \sqrt{11}$
