olya-2409 [2.1K]

Answer:

\left(x^4+3x^3-2x^2+5\right)+\left(2x^4-5x^3+4x-15\right)

= x^4+3x^3-2x^2+5+2x^4-5x^3+4x-15

=x^4+2x^4+3x^3-5x^3-2x^2+4x+5-15

=x^4+2x^4-2x^3-2x^2+4x+5-15

=3x^4-2x^3-2x^2+4x+5-15

=3x^4-2x^3-2x^2+4x-10

What is 5/6+4/3+6+1/4+3/2+9/5-29/12<br><br> With steps?
murzikaleks [220]

Answer:

answer= 229/30

Step-by-step explanation:

turn 4/3 into 8/6

5/6+8/6=13/6

6x6=36

13/6+36/6=49/6

49x2=98

4x3=12

98/12+3/12=101/12

101/12+18/12=119/12

108/60+595/60=10 1/20

10 1/20-29/12=7 19/30

I need help on some geometry questions
kupik [55]

Answer: x = 40

<u>Step-by-step explanation:</u>

3x + x + 20 = 180    <em>same side (consecutive) interior angles</em>

    4x  + 20 = 180

    4x           = 160

      x           = 40

****************************************************************************

Answer: x = 24

<u>Step-by-step explanation:</u>

6x - 24 + 2x + 12 = 180       <em>linear pair (supplementary angles)</em>

               8x - 12  = 180

               8x         = 192

                 x          = 24

****************************************************************************

Answer: x = 16

<u>Step-by-step explanation:</u>

base angles of an isosceles triangle are congruent

2(2x + 15) + 6x - 10 = 180       <em>triangle sum theorem</em>

4x + 30 + 6x - 10 = 180

             10x + 20 = 180

              10x         = 160

                 x          = 16

****************************************************************************

Let ∠1 and ∠2 represent the exterior angles in the diagram and "x" represent the same side (consecutive) interior angle with ∠1.

Then m∠1 + x = 180     <em>same side interior angle theorem</em>

and m∠2 + x = 180      <em>linear pairs are supplementary </em>

m∠1 + x = m∠2 + x     <em>transitive property</em>

m∠1  = m∠2               <em>subtraction property of equality</em>

   ∠1 ≈ ∠2                   <em>definition of congruency</em>

malfutka [58]

Answer:

Original Value= $361.21

Step-by-step explanation:

Giving the following information:

The value of the savings bond increases by 3% each year. One year after it was purchased, the value of the savings bond was $515.

<u>To calculate the original value of the bond, we need to use the following formula:</u>

OV= PV/(1+i)^n

OV= original value

PV= present value

i= increase rate

n= number of months

OV= 515 / (1,03^12)

OV= $361.21
