What is the product of (3x+5) and (x+4)

Mathematics

kodGreya [7K]3 years ago
4 0

For this case we must find the product of (3x + 5) (x + 4)

By definition, the distributive property states that:

(a + b) (c + d) = ac + ad + bc + bd

Then, according to the expression we have:

3x ^ 2 + 12x + 5x + 20 =\\3x ^ 2 + 17x + 20

Answer:

3x ^ 2 + 17x + 20

Option C

Answer:

C

Step-by-step explanation:

Each term in the second factor is multiplied by each term in the first factor, that is

3x(x + 4) + 5(x + 4) ← distribute both parenthesis

= 3x² + 12x + 5x + 20 ← collect like terms

= 3x² + 17x + 20

What is the value of b
n200080 [17]

Angle = 68⁰ is an inscribed angles, this angle equal 68⁰,

so it intersect arc = 2*68⁰= 136⁰.

Arc of the whole circle (circumference) =360⁰,and it also =b+104+136.

b+104+136 =360

b=360-(104+136) = 120⁰

Answer A. b=120⁰.
