Answer:
x = 42
Step-by-step explanation:
The marked angles are supplementary, so their sum is 180°.
(2x +8) +(2x +4) = 180
4x +12 = 180 . . . . . . . . . simplify
x +3 = 45 . . . . . . . divide by 4 (because we can)
x = 42 . . . . . . subtract 3

<em>Additional comment</em>
A "two-step" linear equation like this one is usually solved by subtracting the unwanted constant, then dividing by the coefficient of the variable. Here, we have done those steps in reverse order. This makes the numbers smaller and eliminates the coefficient of the variable. Sometimes I find it easier to solve the equation this way.
Solution:
we have been asked to find
The expression is equivalent to 
we can simplify the given expression as below
Hence the simplified expression , equaivalent to the given expression is 1/2.
2,300,000 + 510,000 = 2,810,000 them move a decimal to where is greater then 1
2.81 x 10^6 but wait, there isnt an answer for this so it has to be 28.1 x 10^5 witch is B
Answer:
Step-by-step explanation:
Parallel line examples in real life are railroad tracks, the edges of sidewalks, marking on the streets, zebra crossing on the roads, the surface of pineapple and strawberry fruit, staircase and railings, etc
Three of those statements are true.
The only one that is NOT correct is:
<span>Any quadrilateral with one right angle is a rectangle.
