First to solve the inequality
300 + 5x > 550
5x > 550 - 300
5x > 250
x > 50
Therefor the answers are all numbers bigger than 50
Answer:
Your answer is 0.3y + 2
Please give mark me as brainliest and have a nice day!<3
44 because the absolute values are 131 and 87 and to find difference you subtract.
Answer: see proof below
<u>Step-by-step explanation:</u>
Use the Double Angle Identity: cos 2A = 2cos²A - 1
Use the Difference Identity: cos (A - B) = cosA · cosB + sinA · sinB
Use the Unit Circle to evaluate: cos (π/2) = 0 & sin (π/2) = 1
<u>Proof LHS → RHS</u>

LHS = RHS: sin A = sin A 
Volume of a cube = a³ = 1728
a = ³√1728
a = 12 mm
In short, Your Answer would be 12 mm
Hope this helps!
