Step-by-step explanation:
The perimeter is the sum of the 3 sides of the triangle , that is
3x + 2x + 6 + 6x - 3 ( simplify by collecting like terms )
= 11x + 3
Given the perimeter = 36 units , then
11x + 3 = 36 ( subtract 3 from both sides )
11x = 33 ( divide both sides by 11 )
x = 3
Then
base = 2x + 6 = 2(3) + 6 = 6 + 6 = 12 units
height = 3x = 3(3) = 9 units
hypotenuse = 6x - 3 = 6(3) - 3 = 18 - 3 = 15 units

Determine the second power
The second power of an expression is the square of the expression.
So, the second power of is
Solving further:
Hence:
Option (c) is correct
(x + 3) is a factor so x = -3 must be a root.
Answer:
x = 8/13
Step-by-step explanation:
6 - 3x - 3/5(15x + 20) = 7(2x/7 - 2) - x
6 - 3x - 9x - 12 = 2x - 14 - x
6 - 12 + 14 = 2x - x + 3x + 9x
8 = 13x
x = 8/13
Point A is the midpoint of CT which means the ratio of CA:CT would be 1:2.
To find CT, you need to find the distance of CA then applies 2 times of the distance to the point C
Xca= Xa-Xc= 1- (-2)= 3
Yca= Ya- Yc= -3 -5= -8
Xt= Xc + 2* Xca= -2 + 2*3= 4
Yt= Yc + 2* Yca= 5 + 2*-8= -11
T(Xt, Yt)= T(4, -11)
The coordinate for point T would be (4, -11)
