170=40x+50 subtract 50
120=40x divide by 40
3=x
Answer:
The equation is,
Step-by-step explanation:
According to the question, the equation is cubic and have roots -1 (with multiplicity of 2) and -2.
So, the equation is,
[Since, when a , b , c are the roots of a cubic equation, the equation is
given by 
]
Answer:
49,152
Step-by-step explanation:
top side=12ft
5 bottom sides=4ft each
2 L,R sides=2ft each
= 12×4×4×4×4×4×2×2
= 49,152
So the change in between terms is 5 so you would put 5x, then for the first term, which is 2, 5*1(x)(because it's first term) then the difference between 5-2(because it's the 2nd term) So you would plug 100 in for x so 5(100)-3=497. Hope this helped!
Answer:
8y = -6
Step-by-step explanation:
Simply add the equations as you would numbers.
The 'x's cancel each other out. The 'y's add together as normal numbers.
9 + (-15) = -6
Hope that this helps!
