Answer:
B
Step-by-step explanation:
Close to equator, hotter and more humid. Alaska not near equator.
Answer:
infinite solutions
Step-by-step explanation:
At first, we try to isolate the x, but adding 4 to -4 on both sides. Both sides have a -4 so it cancels out on both sides of the equation. Similarly, both sides also have a positve 6x, so when we subtract 6x from 6x we get 0. After simplification, we get x = x; x can be any number [ex. 1=1, 2=2, 3=3,etc.], therefore any number can fit into this equation
6x - 4 = -4 + 6x
6x - 4 + 4 = -4 + 4 +6x
6x = 6x
x = x

<h3>1. Write the expression.</h3>
![y=14x^2](https://tex.z-dn.net/?f=y%3D14x%5E2)
<h3>2. Substitute y for x, and x for y.</h3>
![x=14y^{2}](https://tex.z-dn.net/?f=x%3D14y%5E%7B2%7D)
<h3>3. Solve for y.</h3>
![14y^{2}=x\\ \\y^{2} =\frac{x}{14} \\ \\y=\sqrt{\frac{x}{14}}](https://tex.z-dn.net/?f=14y%5E%7B2%7D%3Dx%5C%5C%20%5C%5Cy%5E%7B2%7D%20%3D%5Cfrac%7Bx%7D%7B14%7D%20%5C%5C%20%5C%5Cy%3D%5Csqrt%7B%5Cfrac%7Bx%7D%7B14%7D%7D)

The length of fourth side is: 8a-2
Step-by-step explanation:
Given
Perimeter = P = 39a-7
![Side1 = s_1 =9a\\Side2=s_2=5a+1\\Side3=s_3=17a-6\\Side4=?](https://tex.z-dn.net/?f=Side1%20%3D%20s_1%20%3D9a%5C%5CSide2%3Ds_2%3D5a%2B1%5C%5CSide3%3Ds_3%3D17a-6%5C%5CSide4%3D%3F)
The perimeter is given by:
![P = s_1+s_2+s_3+s_4\\39a-7 =9a+5a+1+17a-6+s_4\\39a-7=31a-5+s_4\\s_4=39a-31a-7+5\\s_4=8a-2](https://tex.z-dn.net/?f=P%20%3D%20s_1%2Bs_2%2Bs_3%2Bs_4%5C%5C39a-7%20%3D9a%2B5a%2B1%2B17a-6%2Bs_4%5C%5C39a-7%3D31a-5%2Bs_4%5C%5Cs_4%3D39a-31a-7%2B5%5C%5Cs_4%3D8a-2)
