Answer: 21
Step-by-step explanation:
9x7=63
63/3=21
The crucial part of the wording of the problem tells us that the two integers are consecutive. So, let's call the first term x. Then the other term must be x + 1 since it comes right after it and is an integer. Now we can solve:
x(x + 1) = x + (x + 1) + 19
x^2 + x = 2x + 20
x^2 - x - 20 = 0
Now we factor:
(x - 5)(x + 4) = 0
This means x either equals 5 or x = -4 to satisfy the above equation. We know that x is positive from the question itself, so x must be 5. The number consecutively after it then must be 6.
Answer:
(x-5) (x-2)
Step-by-step explanation:
x^2 (-2x-5x) +10
basically you will write the equation down and then to double check multiply the x and then the -5 into (x-2). this can be repetitive if you get it wrong so try to do numbers that make sense.
The degree of an expression in more than one variable is the highest sum of the powers of the variables in the terms.
Expression:
An algebraic expression is a combination of constant and variables connected by the signs of fundamental operations.
ex: 2x+5
Degree of an expression:
The degree of an expression in one variable is the highest exponent of the variable in that expression.
Ex:
2x^6 + x^4 + 5
Highest exponent = 6
so degree = 6
The degree of an expression in more than one variable is the highest sum of the powers of the variables.
Ex:
3x^1y^2 + 5x^3y^2 + 5
Sum of powers of variables = 3+2 = 5
Degree = 5.

Answer:
Step-by-step explanation:
We have the product, 
.
As, we have the product of a 3×3 and 3×1 matrix, the resultant matrix will be of order 3×1.
So, we get,
⇒ 
⇒ .
Thus, the resulting product is .
