Choice A is one of the answers. Nice work. This is because x+x+x turns into 3x.
Choice D is the other answer because 2(x+1) + x = 2x+2+x = 3x+2. You can find this through trial and error. Or you could graph y = x+x+x+2 and y = 2(x+1)+2 to find that they are the same exact identical diagonal line. A non-graph approach would be to set up a table of values to see that the two tables are identical.
Answer:Its N and Q
Step-by-step explanation:
The solution to –2(8x – 4) < 2x + 5 is x > 1/6
<h3>How to solve the inequality?</h3>
The expression is given as:
–2(8x – 4) < 2x + 5
Expand
-16x + 8 < 2x + 5
Evaluate the like terms
-18x < -3
Divide both sides by -18
x > 1/6
Hence, the solution to –2(8x – 4) < 2x + 5 is x > 1/6

Answer:
The surface area that Sergio needs to frost on each cake is 3,238 square centimeters
Step-by-step explanation:
The picture of the question in the attached figure
we know that
The surface area of the cylindrical cake is equal to the lateral area plus the area of the top of cylinder (remember that the bottom of the cake does not need frosting)
so

we have
---> the radius is half the diameter


substitute the given values


Round up to the nearest whole number

therefore
The surface area that Sergio needs to frost on each cake is 3,238 square centimeters
