F. determine if (x + 3) is a factor of (x) = 2x3 + x2 –8x + 21 by using synthetic division. if so, find the other factors.
babymother [125]
Since its x + 3 we use -3


-3| 2      1      -8      21           (these are the # without the x)
___________________

            -6     15     -21      
-------------------------------
    2      -5      7        0               
 
Drag the 2 down, multiple it by -3 to get -6 
1+(-6) = -5. -5 * -3 =15 . 15+(-8) = 7
7*-3 = -21. -21 +21 = 0 
Since last # is 0 we have a factor.


 factor is 2x^2 -5x -7 (we start with a power 1 less the original.)

8x = 8+2(x-10)+3x hurry please ill give you brain lesst
rewona [7]

Answer:

x = -4

Step-by-step explanation:

8x = 8 + 2(x-10) + 3x

simplify

8x = 8 + 2x - 20 + 3x

simplify again

8x = 5x - 12

subtract 5x from both sides

3x = -12

divide both sides by 4

x = -4

Subtract the quotient of 18 and 2 from the sum 22 and 9
dexar [7]

Quotient, implies division, so the quotient of 18 and 2 is 6:

18/2=6

Sum implies addition, so the sum of 22 and 9 is 31:
22+9=31

Now we can subtract the quotient of 18 and 2, '6', from the sum of 22 and 9, '31'.

31-6=25

Answer=25

Answer:

\displaystyle \rm  A_{ \text{c  - pentagon}} =41

\rm \displaystyle P _{ \rm c - pentagon} =  20+ 4 \sqrt{2}

Step-by-step explanation:

we have a square and a triangle

we want to figure out the area and the perimeter of the pentagon

to figure out the area of the pentagon we can use the given formula:

\displaystyle \rm  A_{ \text{c  - pentagon}} = A_{ \text{squre}} - A_{ \text{triangle}}

let's figure out A_{\rm square}:

since the given shape is a square Every angle of its 90° Thus the triangle is a right angle triangle

therefore the height is 4

\displaystyle A _{ \rm triangle} =  \frac{1}{2}  \times b \times h

substitute h and b

\displaystyle A _{ \rm triangle} =  \frac{1}{2}  \times 4 \times 4

reduce fraction:

\displaystyle A _{ \rm triangle} =   2 \times 4

simplify multiplication:

\displaystyle A _{ \rm triangle} =   8

likewise square

\displaystyle A _{ \rm squre} =  {s}^{2}

substitute s:

\displaystyle A _{ \rm squre} =  {7}^{2}

simplify square

\displaystyle A _{ \rm squre} =  49

hence,

\displaystyle \rm  A_{ \text{c - pentagon}} =49- 8

\displaystyle \rm  A_{ \text{c  - pentagon}} =41

to figure out perimeter

let's figure out hypotenuse first

\displaystyle h =  \sqrt{ {4}^{2}   +  {4}^{2} }

\displaystyle h =  \sqrt{ 16  +  16}

\displaystyle h = 4 \sqrt{2}

therefore,

\rm \displaystyle P _{ \rm c - pentagon} = 3 + 3 + 4 \sqrt{2}  + 7 + 7

\rm \displaystyle P _{ \rm c - pentagon} = 6 + 4 \sqrt{2}  + 14

\rm \displaystyle P _{ \rm c - pentagon} =  20+ 4 \sqrt{2}
