Answer:
-58
Step-by-step explanation:
If we have the expression
and we know the values of x, y, and z, we can substitute inside the equation to find it's value.
![5\cdot-2\cdot4 - 3\cdot6\\\\-40 - 18\\\\-58](https://tex.z-dn.net/?f=5%5Ccdot-2%5Ccdot4%20-%203%5Ccdot6%5C%5C%5C%5C-40%20-%2018%5C%5C%5C%5C-58)
Hope this helped!

To find a missing length when you have an area and another length you divide the area by the known length
23 4/5 divided by 2 4/5= 8 1/2
Answer:
First you find the radius R
We have, circumference = 2*3.14*R = 31.4
=> R =31.4/(2*3.14) =5
We have , area = 3.14*R^2 = 3.14*5^2 = 78.5
Step-by-step explanation:
Here we use pi =3.14.
