ans show your work thank you

Step-by-step explanation:

They are Alternate angles so they need to be equal to each other meaning you can right them like this;

[tex]4x + 2 = 86[/tex]

So to work out x you just have to separate x;

[tex]4x = 86 - 2 \\ 4x = 84 \\ x = \frac{84}{4} [/tex]

So

[tex]x = 21[/tex]

Answer:

D

Step-by-step explanation:

Every X value can only correspond to one Y value.

For example, in answer A, the Y value 4 is used twice for different X values, so it is not a function.

Answer:

-2x - 7y = -13.    X intercepts = (13/2,0)

3x+6y=15.          Y intercept = (0,13/7)

Step-by-step explanation:

-2x-7y=-13. To find x intercept substitute 0 for y and solve for x.

3x+6y=15.   To find y intercept substitute 0 for x and solve for y.

Answer:

RP = 14

Step-by-step explanation:

(whole secant) x (external part) =  (whole secant) x (external part)

(x+x+2) * (x+2) = (4+6)*4

Combine like terms

(2x+2)(x+2)=10*4

2(x+1)(x+2) = 40

Divide by 2

(x+1)(x+2) = 20

FOIL

x^2+2x+x+2 = 20

x^2 +3x+2 =20

Subtract 20

x^2 +3x-18 = 0

Factor

(x +9) (x-6) = 0

Using  the zero product property

x+9=0   x-6 =0

x= -9    x=6

Since the length cannot be negative

x=6

RP = x+2+x = 6+2+6 = 14

Answer: first, second and fourth are primes, the third is not-prime.

Step-by-step explanation:

A prime polynomial can not be reduced.

Let's see the options:

A) 6x^3 - 5x^2 + 2^x-14

You can see that we have a coefficient equal to 5 and other equal to 2.

As both are prime numbers, we can not reduce this, so this is a prime polynomial.

B) 12x^4 - 18x^2 + 8x^2 - 12 = 12x^4 -10*x^2 + 124

Both coefficients are even, so we can reduce it to:

12x4 -10*x^2 + 124 = 2*(6x^4 -5*x^2 + 72)

So this is not prime.

C) 6x^3 + 9x^2 + 10x + 15

we have that:

6 = 3*2

9 = 3*3

10 = 2*5

15 = 3*5

a polinomial is only reducible if all the coefficients share at least one prime factor, here we can see that this is not the case, so this is a prime polinomial.

D) 12x^2 -3x + 4x + 7 = 12x^2 + x + 7

Again, here we have that one coefficient is 1, the only factor of 1 is itself, so we can not reduce this polinomial, this is prime.

Answer:

answer shown in picture

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

2 pairs of parallel sides. Opposite sides and opposite angles are congruent.

Answer:

y= 2x +8

Step-by-step explanation:

y= 2x+3

gradient of given line = 2

(coefficient of x term when the coefficient of y is 1)

Parallel lines have the same gradient.

Hence gradient of the unknown line is 2.

y= 2x +c

To find the value of c, substitute a coordinate.

When x= 7, y=6,

6= 2(7) +c

6= 14 +c

c= 6-14

c= -8

Thus, the equation of the line is y= 2x +8.

Answer:

B. Kayleigh because she reads at a rate of 6 pages per minute.

Step-by-step explanation:

To find the amount of pages both people read in a minute, we can simply divide:

Jake- 45/9 = 5 pages a minute

Kayleigh- 60/10 = 6 pages a minute

Therefore, Kayleigh reads more pages a minute because 6 > 5.

Answer:

a ) Surface Area ⇒ 222 cm^2, Volume ⇒ 180 cm^3

b ) Surface Area ⇒ 372 cm^2, Volume ⇒ 360 cm^3

c ) Surface Area Increase ⇒ ( About ) 67.56 %, Volume Increase ⇒ 100 %

Step-by-step explanation:

a ) Consider dividing the figure into parts, first solving for the area of the base, using the attachment below for guidance;

As you can see, in the picture I have made it so that the base is nested in a rectangle with dimensions 8 by 5. Calculating the area of this rectangle, subtracting the area of a square with dimensions 2 by 2 cm, we can derive the area of the base in a much quicker manner;

[tex]Area of Base - ( 8 cm * 5 cm ) - ( 2 cm* 2 cm ) = 40 square cm - 4 square cm = \\Solution; Base = 36 square cm[/tex]

Now let us imagine adding the another dimensions to this two dimensional base. That would make a 3 - d prism, with surface area equivalent to mini rectangles and squares with a common dimension being the length of the height; 5 cm

[tex]Area of 1 Square = 5 cm * 5 cm = 25 square cm,\\Area of 2 Square = 25 square cm,\\Area of 1 Rectangle = 3 cm * 5 cm = 15 square cm,\\Area of 2 Rectangle = 15 square cm,\\Area of 3 Rectangle = 2 cm * 5 cm = 10 square cm,\\Area of 4 Rectangle = 10 square cm,\\Area of 5 Rectangle = 10 square cm,\\Area of 6 Rectangle = 8 cm * 5 cm = 40 square cm\\Area of Base 2 = 36 square cm,\\\\Surface Area of Figure = 25 + 25 + 15 + 15 + 10 + 10 + 10 + 40 + 36 + 36 = 222 square cm\\Volume = 36 square cm * 5 cm = 180cubiccm[/tex]

b ) We have calculated the area of the base before, now let us solve for all the " mini shapes " given a new height of 10 cm;

[tex]Area of Rectangle 1 = 5 cm * 10 cm = 50 cm^2,\\Area of Rectangle 2 = 50 cm^2,\\Area of Rectangle 3 = 3 cm* 10 cm = 30 cm^2,\\Area of Rectangle 4 = 30 cm^2,\\Area of Rectangle 5 = 2 cm * 10 cm = 20 cm^2,\\Area of Rectangle 6 = 20 cm^2,\\Area of Rectangle 7 = 20 cm^2,\\Area of Rectangle 8 = 8 cm * 10 cm = 80 cm^2,\\\\Surface Area of Figure = 50 + 50 + 30 + 30 + 20 + 20 + 20 + 80 + 36 + 36 = 372 cm^2\\Volume of Figure = 36 cm^2 * 10 cm = 360 cubic cm[/tex]

c ) Solution; Increase of Surface Area ⇒ ( About ) 67.56 %, Increase of Volume ⇒ 100 %
