Like terms have the same variables and exponents. Constants are also like terms.
The given expression is
Зу + 3y + 5+ 7x^3 - у - 6 - 7x^3
By combining like terms, it becomes
7x^3 - 7x^3 + 3y + 3y - y + 5 - 6
= 5y - 1
Answer:
X= 61 and Y = 34
Step-by-step explanation:
In a rectangle, sine opposite sides are equal, so
3x +21 = 6y and 6y-y = 2x +20
3x - 6y = -21 and 2x -5y = 20
Solve both equation, we get
Y = 34 and X= 61
The answer is 3.45 (C) because 1.15 x 3 = 3.45
Answer:
-15+6 = 5-32
Step-by-step explanation:
If you are asking for the expression of that, then the answer is:-15+6 = 5-32.
Answer:
area is 630
we can multiply 2 1 by 21= 63 by 10=630
