Answer:
Step-by-step explanation:
(s/2)^2+h^2=s^2
h^2=s^2-(s^2/4)
h^2=(3s^2)/4
h=(s/2)(3^(1/2)), s=20
h=10(3^(1/2)) simplest radical form 10 times square root of 3
h=17.32 approximate decimal to nearest one hundredth
Answer:
10
Step-by-step explanation:
since it is a right angle triangle

![x = \sqrt[2]{(5 \sqrt{2} )^{2} +( 5 \sqrt{2})^{2}}](https://tex.z-dn.net/?f=%20x%20%3D%20%20%5Csqrt%5B2%5D%7B%285%20%5Csqrt%7B2%7D%20%29%5E%7B2%7D%20%20%2B%28%205%20%5Csqrt%7B2%7D%29%5E%7B2%7D%7D%20)




Answer:
Plan A would be the least expensive
Step-by-step explanation:
Plan A= $0.45x100= 45, 45+40=$85
Plan B= $0.35x100= 35, 35+70= %105
(Each plan is for 100 minutes)
Answer:
The answer is -(x-3)
Step-by-step explanation:
It can be written as a negative number so it can be divided/cut :
3 - x = -x + 3
= -(x+3)
