We know that m∠1 and m∠2 are congruent because they are alternate interior angles.

This means that
m∠1 = m∠2
7x = 5x + 30

All you have to do is solve for x. The first thing you do is subtract 5x from both sides.
2x = 30
Now divide both sides by 2.
x = 15

The answer is:
2. 15

The perimeter of a parallelogram is 72 meters. The width of the parallelogram is 4 meters less than its length. Find the length
Sidana [21]

Answer:

length = 20 mt

Width = 16 mt

Step-by-step explanation:

Let the length of the field be x

width of the field be y

Hence  formula of the perimeter is given as

P=2(x+y)

P=72(given)

72=2(x+y)

Dividing both sides by 2 we get

x+y=36---(A)

Also given that width of the parallelogram is 4 meters less than its length

Hence  

y=x-4

or x-y=4 ---(B)

Adding A and B  

2x=40

x=20

y=x-4

y=20-4=16

Hence length = 20 mt

Width = 16 mt

PLZ. Using all of my points for this. I need this please help.
podryga [215]

Answer:

6. - 4+2=-2, -2+2=0, -1+2=1 therefore the lower the initial value the higher the result will be. This is because of the fact that x is a negative.


7.  After 5 iterations of the equation -2[x-2]+4 it ended up looping at 1.6 and 3.2, they just kept repeating each other.


8.  This loop is never ending it took me 13 iterations to see that it will works it will result in 2.24 again just as the 3 iteration.  

9.  My function was 4(x)-x^2 with an initial value of 2, after ten times I got a value of 3.51 it looped over and over.

11. I do not notice any type of relationship.

If anyone finds number 10 let me know, I'm stuck.

Hi can someone please find the area of this circle? Thank you!
Alinara [238K]
Answer: 379.94
The diameter is given as 22 inches, the radius would be 2/2 = 11 inches.
Area = 3.14 * 11^2
Area = 3.14 * 121
Area = 379.94 square inches.

Option 3

The solution for given expression is \frac{(x - 4)(x - 4)}{(x + 3)(x + 1)}

<h3><u>Solution:</u></h3>

Given that we have to divide,

\frac{x^2 -16}{x^2 + 5x + 6} \div \frac{x^2 + 5x + 4}{x^2 -2x - 8}   ---- (A)

Let us first factorize each term and then solve the sum

Using a^2 - b^2 = (a + b)(a - b)

x^2 -16 = x^2 - 4^2 = (x + 4)(x -4)  ----- (1)

x^2 + 5x + 6 = (x + 2)(x + 3)   ----- (2)

x^2 + 5x + 4 = (x+1)(x + 4)   ---- (3)

x^2 -2x - 8 = (x-4)(x + 2)   ---- (4)

Now substituting (1), (2), (3), (4) in (A) we get,

\frac{(x + 4)(x -4)}{(x +2)(x +3)} \div \frac{(x+1)(x+4)}{(x-4)(x +2)}

To do division with fractions, we turn the second fraction upside down and change the division symbol to a multiplication symbol at the same time. Then we treat this as a multiplication problem, by multiplying the numerators and the denominators separately.

\frac{(x + 4)(x -4)}{(x +2)(x +3)} \times \frac{(x - 4)(x + 2)}{(x + 1)(x + 4)}

On cancelling terms we get,

= \frac{(x -4)(x-4)}{(x + 3)(x + 1)}

Thus option 3 is correct
