What is the product of (3a + 2)(4a2 – 2a + 9)? 12a3 − 2a + 18 12a3 + 6a + 9 12a3 − 6a2 + 23a + 18 12a3 + 2a2 + 23a + 18

Answers

Answer:

12a3 + 2a2 + 23a + 18

Step-by-step explanation:

Vertical multiplication works well when you have a binomial times a trinomial.

Multiply 2 times the trinomial and get 8a2 - 4a + 18 then multiply 3a times the trinomial to get 12a3. -6a2 + 27a

Then combine like terms.

The product of the givens expressions is 12a³ + 2a² + 23a + 18.

Product of the given expressions

The product of the givens expressions is obtained by multiplying all the variables in the bracket as shown below.

(3a + 2)(4a² – 2a + 9) = 3a(4a² – 2a + 9) + 2(4a² – 2a + 9)

= 12a³ - 6a² + 27a + 8a² - 4a + 18

simplify by collecting similar terms together

= 12a³ + 2a² + 23a + 18

Thus, the product of the givens expressions is 12a³ + 2a² + 23a + 18.

3(2x -5)= 1
And explain

Answers

Answer:

x = 8/3

Step-by-step explanation:

distribute the 3 with everything in the parantheses

3(2x-5) --> 6x -15 = 1

move the 15 to the right side of the equation

6x = 16 and then divide by 6

x = 8/3

Answer:

x = 8/3

Step-by-step explanation:

3 ( 2x - 5 ) = 1

→ Expand out bracket

6x - 15 = 1

→ Add 15 to both sides to isolate 6x

6x = 16

→ Divide both sides by 6 to isolate x

x = 8/3

Answers

Answer:

x=16/3

Step-by-step explanation:

5x−2(x+1)=14

Distribute

5x -2x -2 =14

Combine like terms

3x -2 =14

Add 2 to each side

3x-2+2 =14+2

Step-by-step explanation:

5x - 2(x + 1) = 14

~Simplify

5x - 2x - 2 = 14

~Combine like terms

3x - 2 = 14

~Add 2 to both sides

3x = 16

~Divide 3 to both sides

x = 16/3

Which system of equations is represented by lines s and t?

Answers

Answer:

Step-by-step explanation:

The system of equations is represented by lines s and t will be,3x + 5y = - 18 and 5x - 9y = 25.

What is the equation?

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that,

For S,

x ⇒ -5 2 4

y ⇒ 4 10 22

For T,

x⇒ -4 0 5

y⇒ 14 6 -4

Since the equation represented by lines s and t will be verified by the given value for the x and y.As a result, the equation given in option C satisfies all the given points.

Thus, the system of equations is represented by lines s and t will be,3x + 5y = - 18 and 5x - 9y = 25.

Solve for x

(I’ve tried everything I can think of, but I still haven’t been able to solve this. Please help!)

Answers

Answer:

x = 6

∠2 = 75

Step-by-step explanation:

In the given triangle two sides are equal and so it is an isosceles triangle. So, the angles opposite to equal sides are equal

11x + 9 + 11x + 9 + 30 = 180 {Angle sum property of triangle}

11x + 11x + 9 +9 +30 = 180

22x + 48 = 180

22x = 180 - 48

22x = 132

x = 132/22

x = 6

∠2 = 11*6 + 9 = 66 +9 = 75
