<em>The answer to your problem is:</em>
x = 1/6
Answer:
The answer to your question is A = 441.50 km²
Step-by-step explanation:
Data
Big triangle Small triangle
base = 33 km base = 19 km
height = 40 km height = 23 km
Process
1.- Calculate the area of the big triangle
Area = base x height / 2
Substitution
Area = 33 x 40 / 2
= 1320 / 2
= 660 km²
2.- Calculate the area of the small triangle
Area = 19 x 23 / 2
= 437 / 2
= 218.5 km²
3.- Subtract the small area to the big area
Share area = 660 - 218.5
= 441.50 km²
Answer:
x = 2/3; all real numbers.
Step-by-step explanation:
• hey! •
let's move step-by-step to evaluate these equations.
1. 28 - 6x + 4 = 30 - 3x
- group like terms -
![-6x+28+4=30-3x](https://tex.z-dn.net/?f=-6x%2B28%2B4%3D30-3x)
- add! -
![-6x+32=30-3x](https://tex.z-dn.net/?f=-6x%2B32%3D30-3x)
- subtracting and simplifying -
![-6x=-3x-2](https://tex.z-dn.net/?f=-6x%3D-3x-2)
- simplify -
![\frac{-3x}{-3}=\frac{-2}{-3}](https://tex.z-dn.net/?f=%5Cfrac%7B-3x%7D%7B-3%7D%3D%5Cfrac%7B-2%7D%7B-3%7D)
.
2. 4x - 1 = 9x - 1 - 5x
- add -
![4x-1+1=9x-1-5x+1](https://tex.z-dn.net/?f=4x-1%2B1%3D9x-1-5x%2B1)
- simplify -
![4x=9x-5x](https://tex.z-dn.net/?f=4x%3D9x-5x)
- add -
![4x=4x](https://tex.z-dn.net/?f=4x%3D4x)
thusly,
are solutions to the equation. :)
Answer:
C
Step-by-step explanation:
Answer:
-7
Step-by-step explanation:
Square numbers always have two possible roots: a positive and negative root. This is because two positive numbers multiply to make a positive number and two negative numbers also multiply to make a positive number
-7 × -7 is still 49, just like 7 × 7
Hope this helps!
