Answer:
6x -3x^4
Step-by-step explanation:
Eliminate parentheses. Since the multiplying coefficient is +1, the parentheses can simply be dropped:
= 3x +2x^4 +3x -5x^4
Add like terms (ones with the same exponent on the variable).
= 3x +3x +2x^4 -5x^4 . . . . . . . group like terms together
= (3+3)x +(2-5)x^4
= 6x -3x^4
The length of XZ is likely 8 i think since they are in that order, but idk. sorry if im wrong, and i hope this helped ):
He:other=4:3
22800000=4units
divide both sides by 4
5700000=1unit
times 3 both sides
17100000=3unit=candidates

Well, 4.4 + 7.7 = 12.1
So that would be 12 tonnes
<u>Or </u>
4.4 = 4 tonnes
and
7.7 = 8 tonnes
Hope this helps
Answer:
Step-by-step explanation:
The given system of equations is expressed as
6x - 5y = -34 - - - - - - - - - - - -1
2x + 6y = 4 - - - - - - - - - - - -2
We would eliminate x by multiplying equation 1 by 2 and equation 2 by 6. It becomes
12x - 10y = - 68 - - - - - - - - - - - -3
12x + 36y = 24 - - - - - - - - - - - -4
Subtracting equation 4 from equation 3, it becomes
- 46y = - 92
Dividing the left hand side and the right hand side of the equation by
- 46, it becomes
- 46y/46 = - 92/- 46
y = 2
Substituting y = 2 into equation 2, it becomes
2x + 6 × 2 = 4
2x + 12 = 4
Subtracting 12 from left hand side and the right hand side of the equation, it becomes
2x + 12 - 12 = 4 - 12
2x = - 8
Dividing the left hand side and the right hand side of the equation by 2, it becomes
2x/2 = - 8/2
x = - 4
