Heron's formula is named after Hero of Alexendria, a Greek Engineer and Mathematician in 10 - 70 AD. You can use this formula to find the area of a triangle using the 3 side lengths. Therefore, you do not have to rely on the formula for area that uses base and height. The picture below illustrates the general fro mu la where S represents the semi-perimeter of the triangle ,

X²+x-6=0<br><br>hãy tìm giá trị của x trong câu trên
Gennadij [26K]

Tìm giá trị của x :

  • {x}^{2}  + x  -  6 = 0

  • x {}^{2}  + 3x - 2x  - 6 = 0

  • x(x + 3) - 2(x + 3) = 0

  • (x + 3)(x - 2) = 0

Bây giờ, có hai trường hợp :

Trường hợp 1. khi nào x + 3 = 0

  • x = -3

Trường hợp 2. khi nào x - 2 = 0

  • x = 2

Can someone help pls.
kap26 [50]

<em>My goodness, this is rather confusing in the way it is worded. Nevertheless, I will attempt to do what I can. Just please keep in mind that this is my own interpretation of the problem, and therefore could be... incorrect.</em>

<em>I think, to start out, we could set up the problem like so</em>

<em>15 + t ≥ 26</em>

<em>because t is not a set number. </em>

<em>Then all that is needed is to subtract 15 from both sides, and the equation becomes</em>

<em>t ≥ 11</em>

<em>So the resulting answer is t ≥ 11.</em>

<em />

<em>I hope that my interpretation helps.</em>

How many square feet of paper do you need to cover a cube with a side 10 in. long? Round your answer to two decimal places.
kvv77 [185]
<span>There are 144 square inches in a square foot. The cube you have has sides of 10 inches. First, find how many square feet are equal to one square inch (1/144, or 0.00694r). Then, multiply this by ten to tell you how many square feet you need to cover your cube. This makes 0.07 to two decimal places.</span>
