A square with a side length of 8 inches would have an area of 8*8= 64 inches^2. If the area is multiplied by 36, the new area = 64*36 = 2304 inches^2. To find the new side length of the square, you take the square root of 2304, which equals 48. The side length of the square becomes 48 inches.
Answer:
4 would be $55.00 and 8 would be $75.00
The expression of 25t +45m shows the total number of miles driven at both speeds. In order to solve this equation you would need to know the total number of hours driven in order to multiply that by the appropriate speed in terms of miles per hour.
Hope this helps!
Hello,
First of all , let's see that
![4=2^2\leq 5\leq 9=3^2\\\\2\leq \sqrt{5}\leq 3\\ \\\text{so } (1-\sqrt{5})\leq 0\\ \\\\\text{Then } \sqrt{(1-\sqrt{5})^2}=|1-\sqrt{5}|=\sqrt{5}-1](https://tex.z-dn.net/?f=4%3D2%5E2%5Cleq%205%5Cleq%209%3D3%5E2%5C%5C%5C%5C2%5Cleq%20%5Csqrt%7B5%7D%5Cleq%203%5C%5C%20%5C%5C%5Ctext%7Bso%20%7D%20%281-%5Csqrt%7B5%7D%29%5Cleq%200%5C%5C%20%5C%5C%5C%5C%5Ctext%7BThen%20%7D%20%5Csqrt%7B%281-%5Csqrt%7B5%7D%29%5E2%7D%3D%7C1-%5Csqrt%7B5%7D%7C%3D%5Csqrt%7B5%7D-1)
So,
![\sqrt{6(1-\sqrt{5})^2}=\sqrt{6}(\sqrt{5}-1)=\sqrt{30}-\sqrt{6}](https://tex.z-dn.net/?f=%5Csqrt%7B6%281-%5Csqrt%7B5%7D%29%5E2%7D%3D%5Csqrt%7B6%7D%28%5Csqrt%7B5%7D-1%29%3D%5Csqrt%7B30%7D-%5Csqrt%7B6%7D)
Thanks
X^2+7x+10. i dont know what a middle term is but this is the answer to the equation
