At first find the area of rectangle:
(x + 4)*(x + 1) = x^2 + 5x + 4
Then find the area of triangle:
Then you must do like this
Area of rectangle - Area of triangle = Area of the shaded
x^2+5x+4 - (
)
(x + 4)*(x + 1) = x^2 + 5x + 4
Then find the area of triangle:
Then you must do like this
Area of rectangle - Area of triangle = Area of the shaded
x^2+5x+4 - (
Hey there!
Let's look at our graph here. It is a 4 x 8 chart, which means there are 32 total squares. 12 of these squares are highlighted in black. This gives us 12/32, which is equal to 3/8. Therefore, we can eliminate answer D as an option.
Now, we are looking for a percent of a fraction. Usually when you draw a chart that represents multiplying fractions, the bars will overlap. We do see 5 gray squares, but if that is all, this chart would not really represent anything. Let's say it goes all the way across the top, giving us 8 gray squares, 3 of them also being black.
This means we have 8/32, or 1/4 as our other fraction. As we said before, 3 of these squares are both black and gray. This is 3/32, so the answer to our problem has to be 1/12.
We have fractions 3/8 and 1/4.
Therefore, our answer is H.
I hope this helps!
