.45 is between 0.4 and 0.5
You can solve this problem by using trigonometry. There are two scenarios with a parallelogram with sides 6 and 10. Either the base is 6 or the base is 10. I did both cases and they gave the same results. The answer is B, 45 degrees. My work is shown below:
I’m not sure if you need to find the coordinates, but I’ll leave them here for you.
The upper left corner is at 10, 20.
The bottom left corner is at 10, 5.
The bottom right is 20, 5.
Hope this helps you.
This expression is a generic quadratic expression, so the first thing we need to look at is the last term (-40). Is it negative or positive? What are the factors of it? If the last term is negative, we know that one binomial is a subtraction while the other binomial is an addition. You may be asking, "an addition or subtraction of WHAT?" A binomial factored out of a quadratic expression would look something like this: (x + ____). The blank would equal a factor of the last term. In this case, a pair of factors that would fit is 8 and 5.
8x5 = 40 and -8 + 5 = -3.
Plug it into the binomial example I provided above and....
(x - 8)(x+5)=40
Voila! You have your factored quadratic expression, hope this helps!
