Answers:

  • x = 4
  • AB = 36
  • BC = 36
  • AC = 36

All three sides are 36 units long.

===========================================================

Explanation:

Triangle ABC is equilateral, so all three sides are the same length.

Pick any two of those sides, set them equal to each other, and solve for x

AB = BC

8x+4 = 11x-8

8x-11x = -8-4

-3x = -12

x = -12/(-3)

x = 4

Use this x value to find each side. We should get the same value (if not, then an error occurred in solving for x).

  • AB = 8x+4 = 8*4+4 = 32+4 = 36
  • BC = 11x-8 = 11*4-8 = 44-8 = 36
  • AC = 9x = 9*4 = 36

We get the same value for the three side lengths, so this confirms we have the correct x value.

M is directly proportional to r2 <br> When r=2, m=14<br> Work out the value of m when r=12
Genrish500 [490]

we have M is durectly porpotional to r^2

so M=(k)r^2

and when r=2, m=14

so 14=(k)(2)^2

k=14/4 =7/2

so when r=12

m= (7/2)(12)^2 =(7/2)(144) = 504

The shortest side of an isosceles triangle is 2x - 3 inches long. the longer sides are 6 inches longer than the shortest side. t
Zolol [24]
Side 1 = short side = 2x-3
side 2 = longer side = (short side) + 6 = (2x-3)+6 = 2x+3
side 3 = side 2 = 2x+3

Side 2 and side 3 are the longer two congruent sides

Add up the three sides and set them equal to the given perimeter of 33. Solve for x

(side1)+(side2)+(side3) = perimeter
(2x-3)+(2x+3)+(2x+3) = 33
(2x+2x+2x) + (-3+3+3) = 33
6x+3 = 33
6x+3-3 = 33-3
6x = 30
6x/6 = 30/6
x = 5

If x = 5, then the longer sides are 2*x+3 = 2*5+3 = 10+3 = 13 inches each
(note: the short side is 2*x-3=2*5-3=10-3 = 7 inches)

Answer: 13 inches

Which relation defined by a mapping diagram is not a function?
Schach [20]
If one element in the domain mapped with more then one element in the range, the mapping is called one-to-many relation. One-to-many relations are not functions. Example: Draw a mapping diagram for the function f(x)=2x2+3 in the set of real numbers.
