(3x+1)/(3x+2) = (x+2)/(x-5)

Mathematics
1 answer:
jonny [76]3 years ago
6 0

Answer:

x = -9/22 or -0.409 to the nearest thousandth.

Step-by-step explanation:

Cross multiplying we get:

(3x + 1)(x - 5) = (3x + 2)(x + 2)

3x^2 - 14x - 5 = 3x^2 +8x + 4

3x^2 - 3x^2 - 14x - 8x = 4 + 5

-22x = 9

x = -9/22

Find the surface area of a right triangle prism with legs measuring 3 and 4 and a height of 10.
Hunter-Best [27]
Since we have a rectangle triangle, then we can find the other side of the triangle using the Pythagorean theorem.
 We have then:
 L =  \sqrt{3^2+4^2}
 L =  \sqrt{9+16}
 L =  \sqrt{25}
 L = 5
 Then the surface area is given by the sum of the areas.
 Triangle of the base and the top:
 A1 = (1/2) * (4) * (3)&#10;&#10;A1 = 6
 Rectangle 1:
 A2 = (3) * (10)&#10;&#10;A2 = 30
 Rectangle 2:
 A3 = (4) * (10)&#10;&#10;A3 = 40
 Rectangle 3:
 A4 = (5) * (10)&#10;&#10;A4 = 50
 Finally, the surface area is:
 A = 2A1 + A2 + A3 + A4&#10;
 Substituting values:
 A = 2 * (6) + 30 + 40 + 50&#10;&#10;A = 132
 Answer:
 
The surface area of a right triangle prism is:
