x⁴ + x = 0
x(x³) + x(1) = 0
x(x³ + 1) = 0
x = 0 or x³ + 1 = 0
- 1 - 1
x³ = -1
x = -1
Answer:
Option D, 44
Step-by-step explanation:
<u>Step 1: Find the size of the missing angle</u>
All triangles add up to 180 degrees.
![106 + 30 + x = 180](https://tex.z-dn.net/?f=106%20%2B%2030%20%2B%20x%20%3D%20180)
<u>Step 2: Combine like terms</u>
![(106 + 30) + x = 180](https://tex.z-dn.net/?f=%28106%20%2B%2030%29%20%2B%20x%20%3D%20180)
![136 + x = 180](https://tex.z-dn.net/?f=136%20%2B%20x%20%3D%20180)
<u>Step 3: Subtract 136 from both sides</u>
![136 + x - 136 = 180 - 136](https://tex.z-dn.net/?f=136%20%2B%20x%20-%20136%20%3D%20180%20-%20136)
![x = 44](https://tex.z-dn.net/?f=x%20%3D%2044)

Answer:
C AND A I THINK
Step-by-step explanation:
Answer:
$4100
Step-by-step explanation:
For Kaisha to get this car we have these information available
Amount saved = $1300
The cost of the car = $5400
Let The amount left to complete the car = k
We have this equation
K + $1300 = $5400
K = 5400 - 1300
K = 4100
Therefore Kaisha still needs to earn an additional amount of $4100 for the total amount of the car to be completed.
