Answer:
-2
Step-by-step explanation:
<u>Step 1: Use PEMDAS</u>
z / 6 + x + x - 5
(6)/6 + (1) + (1) - 5
1 + 1 + 1 - 5
3 - 5
-2
Answer: -2
We are asked to express the diagonal of a rectangle in terms of the width in which the area of the polygon is equal to 13 square feet. The area of teh rectangle is equal to length times width. That is 13 = lw; diagonal using pythagorean theorem is sqrt ( l2 + w2). Thus d = sqrt ( (13/w)2 + w2) = sqrt ( (169/w2 + w2) = sqrt ( (169 + w4)/w2) = 1/w sqrt (169 + w4)
The answer is 660 miles in 15 minutes
you would have to multiply 44 by 15
44 x 15
=660

Answer:
![log_372 = 3.8928](https://tex.z-dn.net/?f=log_372%20%3D%203.8928)
Step-by-step explanation:
Given
![log_38 = 1.8928](https://tex.z-dn.net/?f=log_38%20%3D%201.8928)
Required
Evaluate ![log_372](https://tex.z-dn.net/?f=log_372)
We have:
![log_372 = log_3(8 *9)](https://tex.z-dn.net/?f=log_372%20%3D%20log_3%288%20%2A9%29)
Apply law of logarithm
![log_372 = log_38 +log_39](https://tex.z-dn.net/?f=log_372%20%3D%20log_38%20%2Blog_39)
Express 9 as 3^2
![log_372 = log_38 +log_33^2](https://tex.z-dn.net/?f=log_372%20%3D%20log_38%20%2Blog_33%5E2)
Evaluate the exponents
![log_372 = log_38 +2log_33](https://tex.z-dn.net/?f=log_372%20%3D%20log_38%20%2B2log_33)
.
So:
![log_372 = log_38 + 2 * 1](https://tex.z-dn.net/?f=log_372%20%3D%20log_38%20%2B%202%20%2A%201)
![log_372 = log_38 + 2](https://tex.z-dn.net/?f=log_372%20%3D%20log_38%20%2B%202)
Substitute ![log_38 = 1.8928](https://tex.z-dn.net/?f=log_38%20%3D%201.8928)
![log_372 = 1.8928 + 2](https://tex.z-dn.net/?f=log_372%20%3D%201.8928%20%2B%202)
![log_372 = 3.8928](https://tex.z-dn.net/?f=log_372%20%3D%203.8928)
