How many white cubes are there in the bag in fraction form
Hi,
Equation:
![- 7 \times (- 5)](https://tex.z-dn.net/?f=%20-%207%20%5Ctimes%20%20%28-%205%29)
Multiplying two negatives equals a positive.
![( - ) \times ( - ) = ( + )](https://tex.z-dn.net/?f=%28%20-%20%29%20%5Ctimes%20%28%20-%20%29%20%3D%20%28%20%2B%20%29)
Now equation looks like:
![7 \times 5 = 35](https://tex.z-dn.net/?f=7%20%5Ctimes%205%20%3D%2035)
Hope this helps.

50ft! you find the hypotenuse of the triangle so i simplified it down and got the right side angles of 30 ft and 40ft then you do a^2 + b^2 = c^2

Answer:</h2>
a pizza
<h2>
Step-by-step explanation:</h2>
The key in this problem is the word circle. When we talk about a circle we talk about all points included within a circumference and this tells us about surface area. We know that the circumference stands for the points the same distance from the center but this doesn't tell us anything about the area. For a bicycle tire the points are made up from a material that can be rubber, but we haven't any rubber within that circumference, but air. Therefore, we can't calculate an area made of rubber as the area of a circle. So<em> what about a pizza? </em>well, a pizza has food within the circumference, that is, we can calculate an area made of food as the area of a circle
. In conclusion, a pizza is a better illustration for a circle.
Alright, so we can start off by dividing
-4x^2+3xy-y^2 by <span>-(-7x^2-xy+6y^2)=7x^2+xy-6y^2 using long division, getting
-4/7
</span> _____________________
7x^2+xy-6y^2 -4x^2+3xy-y^2
- (-4x^2-4xy/7-24y^2/7)
__________________
25xy/7+31y^2/7
Since we can't do anything at this point, we do
-4/7+(25xy/7+31y^2/7)/(7x^2+xy-6y^2)
At this point, we can divide this by
(x^2+4xy-2y^2), resulting in
(-4/7+((25xy/7+31y^2/7)/(7x^2+xy-6y^2)))/((x^2+4xy-2y^2)). After that, we can't use long division since the numerator's top x exponent is 1.
