Answer:
1) C
2) B
3) A
4) C
5) C
6) C
7) C
8) A
9) D
10) B
Step-by-step explanation:
1) In mathematics, a variable is a symbol or letter, such as "x" or "y," that represents a value.
2) Find the largest exponent the variable has in a polynomial with one variable.
3) A constant term is a term in an algebraic expression that has a value that is constant or cannot change, because it does not contain any modifiable variables. In the algebraic expression x+3, x is the variable and 3 is the constant term.
4) Substitute the value of x in the expression.
2x + 3
= 2(4) + 3
= 8 + 3
= 11
5) Substitute the value of x in the expression.
4x + 2
= 4(5) + 2
= 20 + 2
= 22
6) A polynomial is an algebraic expression with 2 or more terms.
7) A polynomial is an algebraic expression with 2 or more terms.
8) Substitute the value of x and y.
3xy
= 3(0)(1)
= 3(0)
= 0
9) Substitute the value of x.
3
= 3(
)
= 3(9)
= 27
10) Substitute the value of x in the expression.
2x² + 4x - 2
= 2(1²) + 4(1) - 2
= 2(1) + 4(1) - 2
= 2 + 4 - 2
= 6 - 2
= 4
Hope this helps.
