Answer:
-2(a+b)=-2a-2b
Equation is alway true
Rearrange:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
-2*(a+b)-(-2*a-2*b)=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(0 - 2 • (a + b)) - (-2a - 2b) = 0
Step 2 :
Equation at the end of step 2 :
0 = 0
Step 3 :
Equations which are always true :
3.1 Solve 0 = 0This equation is a tautology (Something which is always true)
Equation is alway true

Answer:
5 3/4 + 2 1/4 =y
Step-by-step explanation:
You have to find a common denominator. 12 is the easiest to get in this case. 5/4 * 3= 15/12, 1/3 * 4=4/12. 15/12-72/12+4/12. The answer is 53/12
The correct answer is 8
Because
In triangle ORB
OR=(OB^2-RB^2)^1/2
OR=(17^2-15^2)^1/2
OR=(289-225)^1/2
OR=(64)^1/2
OR=8
RB=AB/2 so I kept its value 15 and ^1/2 refers to square root
