Answer:

c. 3x+1

Step-by-step explanation:

Since the divisor is in the form of x - c, use what is called Synthetic Division. Remember, in this formula, <em>-c</em> gives you the OPPOSITE terms of what they really are, so do not forget it. Anyway, here is how it is done:

4| 3 −11 −4

↓ 12 4

_______________

3 1 0 → 3x + 1

You start by placing the <em>c</em> in the top left corner, then list all the coefficients of your dividend [3x² - 11x - 4]. You bring down the original term closest to <em>c</em> then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than your dividend, so that 3 in your quotient can be a 3x, and the 1 follows right behind it, giving you the quotient of 3x + 1.

I am joyous to assist you anytime.

Answer:

Angela, a proportion is two equal ratios, kinda like 3/4 = 6/8.

 

If we call the number of cars c, then our proportion is 3/10 = c/100.

 

Cross multiplying, we get 10c = 300.

 

Dividing both sides by 10, c = 30.

Answer:

1. x^{2} + x^{2} + (10\cdot x) \cdot (4)

Step-by-step explanation:

(This exercise is written in Spanish and therefore explanation will be held in such language)

El área de este polígono regular es la suma de las áreas de los 4 rectángulos y 2 cuadrados, es decir:

A_{tot} = 4\cdot A_{r} + 2 \cdot A_{c}

A_{tot} = 4 \cdot (10)\cdot x + 2\cdot x^{2}

El cual corresponde con la opción 1.

Solve for X<br> 14 = 3x + 2
Anit [1.1K]
Answer : 4

Explanation : you minus the 2 on both sides bc they have the same "last name" by doing this you get 12 on the left and elimination 2 on the right which leaves you with 12=3x. Divide 3 on both sides which 12/3 =4 and ur left with x. So the final equation is 4=x
