Answer:
Step-by-step explanation:
Here, we can use an angle rule.
We see that angles 
° and 130° are under a sort of F shape, where lines m and n are the horizontal parts of the letter and where the diagonal line is the vertical part of the letter.
This means we can use the rule:
Corresponding angles are equal.
This means that:
We can now use this equation we have formed to solve for 
:
Therefore, our final answer is .
Answer:
You could do 5 x 1 = 5
And for fifty, 5 x 10 = 50
Step-by-step explanation:
Standard form is basically a big or small equation of the numbers
standard form is the usual way of writing numbers in decimal notation, i.e. standard form = 876, expanded form = 800 + 70 + 6, written form = eight hundred seventy six

The length of the rectangle is based on its width, so let's call width w and put the length in terms of the width. We are told that the width is 45 less than 4 times the width, so the length is 4w - 45. Area is found by multiplying length times width and we are given the area as 3325. So we will set up length times width and solve for w, which we will then use to solve for l. 3325 = (4w - 45)(w). Multiplying out we have 
. Move the constant over by subtraction and then we will have a quadratic that can be factored to solve for w. 
. We would put that through the quadratic formula to solve for w. When we do that we get that w = 35 and w = -23.75. The 2 things in math that will never EVER be negative is time and distance/length, so -23.75 is out. That means that the width is 35. The length is 4(35) - 45 which is 95. The dimensions of your rectangle are length is 95 and width is 35. There you go!
In algebra it is fully possible for x to equal to zero. After you have 2x, just divide both sides by two, so it would be 2 divided by 0 and than you would have x=0 and that would be your final answer.
2x + 1 = 4x +1
-2x +1 = 1
-2x = 0
divide by -2
x=0
