Answer:
<em>i: </em>x=-2, x=1
<em>ii: </em>x=-1/2
Step-by-step explanation:
Quadratic form:
You solve <em>i </em>by using FOIL (First, Outside, Inside, Last) because it is a multiplication problem.

<em>"first"</em> would be
, which would equal 
<em>"outside"</em> would be
, which would equal 
<em>"inside"</em> would be
, which would equal 
<em>"last" </em>would be
, which would equal 
Now you need to combine the terms so that they are one after the other

Combine like terms, and you should get:

i Solution
<em>You need to get the variable by itself.</em>
<em>Subtract two from both sides</em>

<em>Add one to both sides.</em>

ii Solution
<em>Add all the terms.</em>

Step-by-step explanation:
<h2>Q: 25-(3x+5)=2(x+8)+x</h2>
- 25-3x-5=2x+16+x
- 20-6x=16
- 6x=4
- x=2/3
Yes, 3 yards is bigger than 21 feet because there are 3 feet in a yard.
Answer:
Two-tailed test.
Step-by-step explanation:
There are two types of tests:
One-tailed tests and two-tailed tests.
When we only test if the mean is less or more than a value, we have a one-tailed test.
When we test if the mean is different from a value, we have a two-tailed test.
If you were to conduct a test to determine whether there is evidence that the proportion is different from 0.30, which test would you use?
Test if it is different, so a two-tailed test.
The value of x is 1.
* Let's explain how to solve the problem
- Line PU has points R and S between points P and U
- Line QR intersects line PU at point R
- Line ST intersects line PU at point S
- Lines QR and ST are parallel
- Look to the attached figure
∵ QR // ST
∴ m∠TSU = m∠QRU ⇒ corresponding angles
∵ m∠TSU = 15(x + 2)°
∴ m∠QRU = 15(x + 2)
∵ Points P, R, S lie on the same line
∵ RQ intersects PS at R
∵ m∠PRQ + m∠QRU = 180° ⇒ straight angle
∵ m∠PRQ = 135°
∵ m∠QRU = 15(x + 2)°
∴ 135 + 15(x + 2) = 180
∴ 135 + 15x + 30 = 180
- Add like terms
∴ 15x + 165 = 180
- Subtract 165 from both sides
∴ 15x = 15
- Divide both sides by 15
∴ x = 1
∴ The value of x is 1
In geometry, parallel lines are coplanar instantly traces that do not intersect at any factor. Parallel planes are planes in identical three-dimensional space that in no way meet. Parallel curves are curves that do not touch every different or intersect and hold a set minimal distance
In mathematics, the intersection of or more gadgets is any other item that includes the whole thing that is contained in all the items simultaneously.
