2=6
3=9
9=27
You just times the number in box X three times
What do you need help with?
So you got
z²+y²=25² and
17²+x²=z²
x²+6²=y²
nice, so we have z² and y² all in terms of x
17²+x²+x²+6²=25²
2x²+289+36=625
2x²=300
x²=150
x=5√6
if we input back to find y and z
17²+x²=z², 287+150=z², √439 =z
x²+6²=y², 150+36=y², √186=y (not simplifying because no graphing calculator, so just eimplify yourself)
Answer:
27.38
Step-by-step explanation:
This is the answer because:
1) Standard form means to write the full number
2) First we have to multiply because we have to use order of operations
3) So do 2 x 10 which is 20
4) Then, do 7 x 1 which is 7
5) Next, do 3 x 0.1 which is 0.3
6) Finally, do 8 x 0.01
The new equation is:
20 + 7 + 0.3 + 0.08
This expression equals to 27.38
Therefore, the answer is 27.38
Hope this helps!
