Answer:

x = 8

y = 30

Step-by-step explanation:

5x = 40 degrees ( alternate interior angle).

so x = 8

And as the angle adjacent to 40 degrees is 90-50 then

3y = 180 - 50 - 40

3y = 90 degrees

y = 90/3

y = 30

A simpler way to find y is

3y = 90 ( 2 inside angles between parallel lines add up to 180)

so y = 30

Does anyone know the answer?

Answer:

We conclude that the area of the right triangle is:

$A\:=p^2-2p-3$

Hence, option A is correct.

Step-by-step explanation:

From the given right-angled triangle,

Base = p+1

Perpendicular = 2p-6

Using the formula to determine the area of the right-angled triangle

Area of the right triangle A = 1/2 × Base × Perpendicular

$=\frac{1}{2}\left(p+1\right)\left(2p-6\right)$

Factor 2p-6: 2(p-3)

$=\frac{\left(p+1\right)\times \:2\left(p-3\right)}{2}$

Divide the number: 2/2 = 1

$=\left(p+1\right)\left(p-3\right)$

$\mathrm{Apply\:FOIL\:method}:\quad \left(a+b\right)\left(c+d\right)=ac+ad+bc+bd$

$=pp+p\left(-3\right)+1\cdot \:p+1\cdot \left(-3\right)$

$=pp-3p+1\cdot \:p-1\cdot \:3$

$=p^2-2p-3$

Therefore, we conclude that the area of the right triangle is:

$A\:=p^2-2p-3$

Hence, option A is correct.

Can I see how long division works on these? pls no sketchy links

Answer:

Step-by-step explanation:

11) First write in decreasing exponential terms and fill in blanks with zeros.

Our goal is to eliminate all term in the dividend by subtraction

________________

2v - 2 | 2v³ - 16v² + 0v + 13

we see that 2v needs to be multiplied by 1v² to eliminate the first term

v²

2v - 2 | 2v³ - 16v² + 0v + 13

- (2v³ - 2v²)

0 - 14v²

multiply your estimate by your divisor and subtract from the dividend.

bring down the next term and repeat.

v² -7v

2v - 2 | 2v³ - 16v² + 0v + 13

- (2v³ - 2v²)

0 - 14v² + 0v

-(-14v² + 14v)

- 14v

repeat again

v² - 7v - 7

2v - 2 | 2v³ - 16v² + 0v + 13

- (2v³ - 2v²)

0 - 14v² + 0v

-(-14v² + 14v)

- 14v + 13

-(-14v + 14)

-1

and remainder gets put over the divisor and appended

v² - 7v - 7 - 1/(2v - 2)

13) Same process

5a + 1 | 40a³ - 12a² - 39a - 5

8a²

5a + 1 | 40a³ - 12a² - 39a - 5

-(40a³ + 8a²)

-20a² - 39a

8a² - 4a

5a + 1 | 40a³ - 12a² - 39a - 5

-(40a³ + 8a²)

-20a² - 39a

-(-20a² - 4a)

-35a - 5

8a² - 4a - 7

5a + 1 | 40a³ - 12a² - 39a - 5

-(40a³ + 8a²)

-20a² - 39a

-(20a² - 4a)

-35a - 5

-(-35a - 7)

8a² - 4a - 7 + 2/(5a + 1)
