Answer:
x = 5/7
Step-by-step explanation:
(7^x)^4) = 7^2 * 7^3 / 7^3x
1. Simplify the expression
(7^x)^4) becomes 7^4x
7^2 * 7^3 becomes 7^5
7^5/7^3x becomes 7^5 - 7^3x
Your new equation: 7^4x = 7^5 - 7^3x
2. Since the bases(7) are the same set the exponents equal to each other
4x = 5 - 3x
3. Combine like terms
4x + 3x = 5
7x = 5
4. Divide both sides by 7 to get x by itself
x = 5/7
Answer: - 4
because The temperature at 2 am was -12 degrees and At noon the temperature had risen 16 degrees
=> the temperature at noon was -12 + 16 = 4 (degrees)
At 4 pm the temp dropped 8 degrees => the temperature at 4 pm was:
4 - 8 = -4 (degrees)

Answer: B: 0.81 miles
Step-by-step explanation:
The find the total distance, you must look for firs the missing side. To get use the formula that is derived from the Pythagorean theorem which states that the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
The formula for this is: a^2 + b^2 = c^2
So let the first side or a be .19
and the second side be .28
and now we are looking for c which is the missing side
.19^2 + .28^2 = c^20.0361 + 0.784 = .1145
get the square root of .1145
√.1145 = it is approximately 0.34
get the total distance by adding three sides
= .34 + .19 + .28
= 0.81
