Answer:
x = 8
Step-by-step explanation:
since the triangle is isosceles then the 2 legs are congruent, that is both 4x - 3
the perimeter is the sum of the 3 sides , that is
x + 4x - 3 + 4x - 3 = 66
9x - 6 = 66 ( add 6 to both sides )
9x = 72 ( divide both sides by 9 )
x = 8
The equation should be
j = 30 + 3a
j + a = 210
Solving the equation
j + a = 210
(30 + 3a) + a = 210
30 + 4a = 210
4a = 180
a = 45
j = 30 + 3a
j = 30 + 3 × 45
j = 30 + 135
j = 165
Aiden's weight is 45 pounds, Jonathan's weight is 165 pounds
Answer:
The numbers are 4 and 5
Step-by-step explanation:
Let
x------> the smaller number
x+1----> the bigger number
we know that
----> equation that represent the situation
solve for x
![\sqrt{x}=(x-2)](https://tex.z-dn.net/?f=%5Csqrt%7Bx%7D%3D%28x-2%29)
squared both sides
![x=(x-2)^{2}\\x=x^{2}-4x+4\\x^{2}-5x+4=0](https://tex.z-dn.net/?f=x%3D%28x-2%29%5E%7B2%7D%5C%5Cx%3Dx%5E%7B2%7D-4x%2B4%5C%5Cx%5E%7B2%7D-5x%2B4%3D0)
using a graphing calculator to solve the quadratic equation
see the attached figure
the solution is
![x=4](https://tex.z-dn.net/?f=x%3D4)
![x+1=5](https://tex.z-dn.net/?f=x%2B1%3D5)
