When we multiply or divide by a negative to solve an inequality, it's the same as multiplying or dividing by a negative to solve a regular equation! Just remember to multiply or divide both sides by the same quantity, then simplify! Remember, when multiplying or dividing by a negative YOU MUST FLIP THE INEQUALITY SIGN.

You flip the inequality.
Example: if x > -y and you divide both sides by (-1) then you flip the inequality so: -x < y

4/6 x what equals 8/6​
Sidana [21]

Answer: 4/6

1. Subtract 8/6 by 4/6.

  • 8/6 - 4/6 = 4/6

4/6 + 4/6 = 8 is the same as:

  • 4 + 4 = 8

<em>Notice: You don't change the denominator if your adding or subtracting.</em>

<em>That's why 4 + 4 = 8 is the same as 4/6 + 4/6.</em>

<em />

<h2>Final answer: 4/6. </h2>

Find the surface area of this net.
Elden [556K]

Answer:

<h2>231cm²</h2>

Step-by-step explanation:

First, let's find the surface area of both the triangles

5x3=15

So, the surface area of the triangles is 15 sq.cm

Now, let's find the surface area of the base (large rectangle in the middle)

12x8=?

10x8=80

2x8=16

80+16=96

12x8=96

So, the surface area of the base, is 96sq.cm

Now, let's find the surface area of both of the side rectangles

12x5=60

60x2=120

So, the surface area of the two side rectangles is 120sq.cm

Now, let's find the total surface area by adding all of our answers.

120+96=216

216+15=231

<h2>So hence, the surface area of this net is 231cm²</h2>
