Answer:
r = Q/(8s^2)
Step-by-step explanation:
Divide by the coefficient of r.
Q/(8s^2) = 8rs^2/(8s^2) = r
Answer:
It is the last one.
Step-by-step explanation:
With a problem like this you must rank highest to lowest and add anything that has the same look. Take 2squared and 5 squared for example, They both are squared so you can add them. Hope this Helped.
Answer:
A= 150°
B=30°
C=150°
Step-by-step explanation:
Since a line is 180°, you can write an equation for C. C+30°=180° , from here use algebra to find C. The value of C will be 150°. When the value of C is 150° , since they're supplementary angles, the value of A will also be 150°.
Important thing to note:
The value of all these angles combined together is 360°.
2(3+3) or 2(3)+6, so the answer is the third option. It’s just using the distributive property.
