If you expand and simplify (2x+3)(x+4)

Answers

Answer 1

Answer:

Answer:

The answer is 2x² + 11x + 12.

Step-by-step explanation:

You have apply Distributive Law,

$a(m + n) = am + an$

So for this question :

$(2x + 3)(x + 4)$

$= 2x(x) + 2x(4) + 3(x) + 3(4)$

$= 2 {x}^(2) + 8x + 3x + 12$

$= 2 {x}^(2) + 11x + 12$

Answer 2

Answer:

$(2x + 3)(x + 4) \n = 2x(x + 4) + 3(x + 4) \n = 2x * x + 2x * 4 + 3 * x + 3 * 4 \n = {2x}^(2) + 8x + 3x + 12 \n = {2x}^(2) + 11x + 12 \n hope \: it \: helps$

What is the solution to the proportion? Round the answer to the nearest tenth if necessary. StartFraction 52 over x EndFraction = StartFraction 9.5 over 3.25 EndFraction x = 14.6 x = 17.8 x = 157.8 x = 169.0

Answers

The solution to the proportion would be x = 17.8 which is the correct option (B).

What is Ratio?

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other

What are Arithmetic operations?

Arithmetic operations can also be specified by adding, subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operations is called the arithmetic operator.

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

We have been the given proportion as:

⇒ 52 : x = 9.5 : 3.25

⇒ 52/x = 9.5/3.25

⇒ 52/x = 2.923

Cross multiplication, and we get

⇒ x = 52/2.923

Apply the division operation,

⇒ x = 17.8

Therefore, the solution to the proportion would be x = 17.8.
