Let's work through the problems in the image step by step:

Problem 1:

The equation given is:

$10x + 3y + Bx - y$

The instructions ask to determine: a. Variables
b. Coefficients
c. Constants
d. Factors
e. Terms (Suku-Suku)

a. Variables:

The variables are the letters that represent unknown quantities. In the given equation, the variables are:

• $x$
• $y$
• $B$ (assuming B is a constant coefficient)

b. Coefficients:

The coefficients are the numbers multiplying the variables. In this case:

• For $10x$, the coefficient is 10.
• For $3y$, the coefficient is 3.
• For $Bx$, the coefficient is $B$.
• For $-y$, the coefficient is -1 (since no number is explicitly written).

c. Constants:

Constants are numbers or symbols without variables. In this expression, no standalone constant (a number without any variable) is present, unless we assume that $B$ is a known number.

d. Factors:

Factors are quantities that multiply to form terms. For example:

• In $10x$, the factors are 10 and $x$.
• In $3y$, the factors are 3 and $y$.
• In $Bx$, the factors are $B$ and $x$.
• In $-y$, the factors are -1 and $y$.

e. Terms (Suku-Suku):

The terms are separated by plus or minus signs. The given expression has 4 terms:

• $10x$
• $3y$
• $Bx$
• $-y$

Problem 2:

The second problem asks to determine which of the following expressions have like terms ("Suku-Suku Sejenis"). Like terms have the same variables raised to the same powers.

Let's check the given options:

• a. $4p - 4p$
  These are like terms because both terms involve $p$, and they are raised to the same power (1).

• b. $3x^2 + 2y^2$
  These are not like terms because one term involves $x^2$ and the other involves $y^2$, different variables.

• c. $2xy - xy$
  These are like terms because both terms involve $xy$, the same combination of variables.

• d. $8p - 9$
  These are not like terms because one term involves $p$ and the other is a constant.

• e. $14p^2 - 9p$
  These are not like terms because the first term involves $p^2$ and the second term involves $p$.

• f. $7p - 8p$
  These are like terms because both terms involve $p$.
