Solve the equation by using the quadratic formula.<br> 8x2 – 2x - 15 =0

ddd [48]

Answer:

x = 3/2 or x = -5/4

Step-by-step explanation:

Solve for x over the real numbers:

8 x^2 - 2 x - 15 = 0

Using the quadratic formula, solve for x.

x = (2 ± sqrt((-2)^2 - 4×8 (-15)))/(2×8) = (2 ± sqrt(4 + 480))/16 = (2 ± sqrt(484))/16:

x = (2 + sqrt(484))/16 or x = (2 - sqrt(484))/16

Simplify radicals.

sqrt(484) = sqrt(4×121) = sqrt(2^2×11^2) = 2×11 = 22:

x = (2 + 22)/16 or x = (2 - 22)/16

Evaluate (2 + 22)/16.

(2 + 22)/16 = 24/16 = 3/2:

x = 3/2 or x = (2 - 22)/16

Evaluate (2 - 22)/16.

(2 - 22)/16 = -20/16 = -5/4:

Answer: x = 3/2 or x = -5/4

What is the total surface area of the box formed by the pattern below

nadezda [96]

Answer:

<h2>The total surface area of the box is 224 square inches.</h2>

Step-by-step explanation:

The box pattern is shown in the image attached.

The total surface is the sum of the area of each section of the figure, which is formed by 4 equal rectangles and 2 equal squares. Rectangles have dimensions of 12 inches by 4 inches, and squares have 4 inches per side.

So, the total surface would be

$S_{total}=S_{squares} +S_{rectangles}\\ S_{total}=2(4in)^{2} +4(12in \times 4 in)\\ S_{total}=2(16in^{2})+4(48in^{2} ) \\ S_{total}=32in^{2}+192in^{2}\\ S_{total}=224in^{2}$

Therefore, the total surface area of the box is 224 square inches.
