Answer:
it must be number 1
I am sure about parallel side and 4 right angles
<u>Answer (1):</u>
Coefficient of any term means the number multiplied in that term including sign.
is same as
.
Hence required coefficient is 1.
<u>Answer (2):</u>
![4(3-7)^2+102](https://tex.z-dn.net/?f=4%283-7%29%5E2%2B102)
![=4(-4)^2+102](https://tex.z-dn.net/?f=%3D4%28-4%29%5E2%2B102)
![=4(16)+102](https://tex.z-dn.net/?f=%3D4%2816%29%2B102)
![=64+102](https://tex.z-dn.net/?f=%3D64%2B102)
![=166](https://tex.z-dn.net/?f=%3D166)
Hence final answer is 166
<u>Answer (3):</u>
![\sqrt{\frac{49}{25}}](https://tex.z-dn.net/?f=%5Csqrt%7B%5Cfrac%7B49%7D%7B25%7D%7D)
![=\frac{\sqrt{49}}{\sqrt{25}}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B%5Csqrt%7B49%7D%7D%7B%5Csqrt%7B25%7D%7D)
![=\frac{7}{5}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B7%7D%7B5%7D)
Hence final answer is ![\frac{7}{5}](https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B5%7D)
11.25cups. I got that by multiplying 2.5. by 4.5. If she wants to make 4.5 batches and 1 batch uses 2.5 cups, you have to multiply the cups of 1 batch by the number of batches she wants to make.
