I have included attachment below
so since a rhombus is 2 pairs of paralell sides, we can cut it into 4 triangles
we can see that we can take the bottom 2 triangles and put them on top to get a rectangle that is width 21 and height 32/2 (16=height
area of rectangle=legnth times width=16 times 21=336 m^2
answer is 336 m^2

![Girls = 18](https://tex.z-dn.net/?f=Girls%20%3D%2018)
Step-by-step explanation:
Given
![G:B= 3:4](https://tex.z-dn.net/?f=G%3AB%3D%203%3A4)
![Total = 42](https://tex.z-dn.net/?f=Total%20%3D%2042)
Required
Determine the number of boys and girls
We have to convert the ratio to fraction;
Number of girls can be calculated as:
![Girls = \frac{G}{G + B} * Total](https://tex.z-dn.net/?f=Girls%20%3D%20%5Cfrac%7BG%7D%7BG%20%2B%20B%7D%20%2A%20Total)
![Girls = \frac{3}{3 + 4} * 42](https://tex.z-dn.net/?f=Girls%20%3D%20%5Cfrac%7B3%7D%7B3%20%2B%204%7D%20%2A%2042)
![Girls = \frac{3}{7} * 42](https://tex.z-dn.net/?f=Girls%20%3D%20%5Cfrac%7B3%7D%7B7%7D%20%2A%2042)
![Girls = 3 * 6](https://tex.z-dn.net/?f=Girls%20%3D%203%20%2A%206)
![Girls = 18](https://tex.z-dn.net/?f=Girls%20%3D%2018)
![Boys = Total - Girls](https://tex.z-dn.net/?f=Boys%20%3D%20Total%20-%20Girls)
![Boys = 42 - 18](https://tex.z-dn.net/?f=Boys%20%3D%2042%20-%2018)
![Boys = 24](https://tex.z-dn.net/?f=Boys%20%3D%2024)
1,300 students will be left
Answer:
76
Step-by-step explanation:
Move 22 to the left side of the equation by adding it to both sides.3x2−10x+2=03x2-10x+2=0The discriminant of a quadratic is the expression inside the radical of the quadratic formula.b2−4(ac)b2-4acSubstitute in the values of aa, bb, and cc.(−10)2−4(3⋅2)-102-43⋅2Evaluate the result to find the discriminant. hope this helps :)
