Question

2. The value of 3x(x + 5) is:

(a) 3x²+ 5
(b) 3x²+ 15x
(c) 15x²
(d) 3x + 15​

Answer 1

Answer:

C

Step-by-step explanation:

in PEMDAS the parenthesis came first meanjbg

(x+5) = 5x

3x(5x) = 15x²

Given:

2. The value of 3x(x + 5) is:

(a) 3x²+ 5

(b) 3x²+ 15x

(c) 15x²

(d) 3x + 15

it is a simple multiplication of algebraic expression.

To solve the sum we know some general rules of multiplication of algebraic expression.

=>1) product of monomial and bionomial is a bionomial

2) monomial is a algebraic expression who contents one term

3) bionomial is a algebraic expression who contents two terms.

here 3x(x+5)

=3x²+15x

we know that 3x²+15x is a bionomial and in early we already said that product of a monomial and bionomial is a bionomial
