(6x3 + 3x² + 3) + (2x - 5x + 1)<br> the sum is?
laiz [17]
<h2>Answer:</h2><h2><em><u>8x^3 + 3x^2 - 5x + 4 is the answer.</u></em></h2>

Step-by-step explanation:

(6x^3 + 3x² + 3) + (2x^3 - 5x + 1)

6x^3 + 2x^3 = 8x^3

3x^2 + 0 = 3x^2

-5x + 0 = -5x

3 + 1 = 4

8x^3 + 3x^2 - 5x + 4 is the answer because you have to put all the terms that were solved together. This will lead to 8x^3 + 3x^2 - 5x + 4. And, standard form is ax^2 + bx + c. So, 8x^3 + 3x^2 - 5x + 4 is the answer.

<em><u>8x^3 + 3x^2 - 5x + 4</u></em>

<em><u></u></em>

Hope this helped,

Don tracked the price of gas for several months. In January gas cost $2.65, in February the price had risen $0.56, in March decr
Elan Coil [88]
Starting price is 2.65, increased by .56

2.65+.56=3.21

Price is 3.21, decreased by .23

3.21-.23=2.98

Price is 2.98, increased by 1.02

2.98+1.02= 4

Price is 4, decreased by .48

4-.48=3.52

Now find the difference from the starting price (January) from the end price (May)

3.52-2.65=.87

<u>The difference from gas prices is $.87</u>

Point A is at (-2,-7) and point M is at (2.5, -1.5).
algol [13]

Answer:

B(7 , 4)

Step-by-step explanation:

(x₁ , y₁) = A(-2 , -7)

(x₂ , y₂) = Point B

Midpoint(5.5, -1.5)

Midpoint= (\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})\\\\\\(\frac{-2+x_{2}}{2} , \frac{-7+y_{2}}{2} = (2.5 , -1.5)

Compare x-coordinates  & y-coordinates

\frac{-2+x_{2}}{2}=2.5     ;  \frac{-7+y_{2}}{2}=-1.5

-2+ x₂ = 2.5*2     ; -7+ y₂ = -1.5*2

-2+ x₂ = 5            ; -7 +y₂ = -3

    x₂ = 5 +2       ;        y₂ = -3 + 7

    x₂  = 7            ;        y₂ = 4

B(7 , 4)
