8x+15=7
In the statement the phrase the sum of can tell you that it is going to be an addition problem. So 8x ( eight times a number) would be added to the 15, 8x+15. Since its an addition problem the part where it says ' ... is seven', you know that it will all equal 7. So the answer would be 8x+15=7.
The delivery driver has to make deliveries at 5 locations <span>among the 6 locations. </span>This means the order of the probability is important because the route he will take from A to B is different with A to C.
So, you need to use permutation for this problem. The calculation would be:
6P5= 6!/ (6-5)!= 720 different routes
Answer:
-1=y
Step-by-step explanation:
Triangle: 13.3 km Why: the formula is 1/2 base x height.
Square: 57.4 Why: 7x8.2 which equals 57.4
The choices are equivalent to the expression correct choices are A, C, and D.
The given expression is
x^3 /5

What is the expression?</h3>
The expression consists of numbers and arithmetic operators. It does not contain equality or inequality symbols.
<h3>What is the power rule?</h3>
![a^{\frac{m}{n} =\sqrt[n]{a^m}](https://tex.z-dn.net/?f=a%5E%7B%5Cfrac%7Bm%7D%7Bn%7D%20%3D%5Csqrt%5Bn%5D%7Ba%5Em%7D)
Therefore the above power rule implies that,
![x^{(\frac{3}{5}) }=\sqrt[5]{x^3}](https://tex.z-dn.net/?f=x%5E%7B%28%5Cfrac%7B3%7D%7B5%7D%29%20%7D%3D%5Csqrt%5B5%5D%7Bx%5E3%7D)
Also, we have the power rule
or it can be written as
![x^{\frac{3}{5} =(\sqrt[5]{x})^3](https://tex.z-dn.net/?f=x%5E%7B%5Cfrac%7B3%7D%7B5%7D%20%3D%28%5Csqrt%5B5%5D%7Bx%7D%29%5E3)
The correct choices are A, C, D.
