Answer:
7^5 (the arrow means it is an exponent)
Answer:
im nt quite sure lets wrok it out
If 8 is added twice a number and this sum is multiplied by 4, the same result is the same as if the number is multiplied is added to the product
Step-by-step explanation:
164 would be the awnser
Answer:
1) Get rid of grouping symbols like square brackets and parentheses
2) Simplify both sides of the equation. Combine like terms if possible.
3) Choose where you want to keep the variable because that will help you decide where to place the constant.
4) Eliminate numbers or variables by using opposite operations. Remember that addition and subtraction are opposites and so are multiplication and division.
Step-by-step explanation:
5+5=10
3+1+1=10
1+1+1+1+1=10

Step-by-step explanation:
Given two expressions:
![2(s+0.5)+2(s+1.5)](https://tex.z-dn.net/?f=2%28s%2B0.5%29%2B2%28s%2B1.5%29)
and
![4\left(\dfrac{1}{2}s+\dfrac{1}{4}s\right)+4](https://tex.z-dn.net/?f=4%5Cleft%28%5Cdfrac%7B1%7D%7B2%7Ds%2B%5Cdfrac%7B1%7D%7B4%7Ds%5Cright%29%2B4)
a. When ![s=0,](https://tex.z-dn.net/?f=s%3D0%2C)
then
![2(s+0.5)+2(s+1.5)=2(0+0.5)+2(0+1.5)=1+3=4](https://tex.z-dn.net/?f=2%28s%2B0.5%29%2B2%28s%2B1.5%29%3D2%280%2B0.5%29%2B2%280%2B1.5%29%3D1%2B3%3D4)
and
![4\left(\dfrac{1}{2}s+\dfrac{1}{4}s\right)+4=4\left(\dfrac{1}{2}\cdot 0+\dfrac{1}{4}\cdot 0\right)+4=4](https://tex.z-dn.net/?f=4%5Cleft%28%5Cdfrac%7B1%7D%7B2%7Ds%2B%5Cdfrac%7B1%7D%7B4%7Ds%5Cright%29%2B4%3D4%5Cleft%28%5Cdfrac%7B1%7D%7B2%7D%5Ccdot%200%2B%5Cdfrac%7B1%7D%7B4%7D%5Ccdot%200%5Cright%29%2B4%3D4)
b. When ![s=12,](https://tex.z-dn.net/?f=s%3D12%2C)
then
![2(s+0.5)+2(s+1.5)=2(12+0.5)+2(12+1.5)=2\cdot 12.5+2\cdot 13.5=25+27=52](https://tex.z-dn.net/?f=2%28s%2B0.5%29%2B2%28s%2B1.5%29%3D2%2812%2B0.5%29%2B2%2812%2B1.5%29%3D2%5Ccdot%2012.5%2B2%5Ccdot%2013.5%3D25%2B27%3D52)
and
![4\left(\dfrac{1}{2}s+\dfrac{1}{4}s\right)+4=4\left(\dfrac{1}{2}\cdot 12+\dfrac{1}{4}\cdot 12\right)+4=4(6+3)+4=4\cdot 9+4=36+6=40](https://tex.z-dn.net/?f=4%5Cleft%28%5Cdfrac%7B1%7D%7B2%7Ds%2B%5Cdfrac%7B1%7D%7B4%7Ds%5Cright%29%2B4%3D4%5Cleft%28%5Cdfrac%7B1%7D%7B2%7D%5Ccdot%2012%2B%5Cdfrac%7B1%7D%7B4%7D%5Ccdot%2012%5Cright%29%2B4%3D4%286%2B3%29%2B4%3D4%5Ccdot%209%2B4%3D36%2B6%3D40)
c. Since the value of both expressions at s = 12 are different, the expressions are not equivalent.
