Please help I'm so confused! I need the surface area. Thank you
kondaur [170]

Answer:

The answer is : 23.25 in ²

Step-by-step explanation:

There are 3 triangles with the same lengths: height = 5in and base = 5 in

There is one triangle: height = 4.3 in base = 5 in

Formula

Area = height x base / 2

For the triangles

Area = 5 in x 5 in /2 = 25 /2 = 12.5 in²

For the triangle

Area = 4.3 x 5 /2 = 21.5 /2 = 10.75 in²

Total surface area = 12.5 + 10.75 = 23.25 in²

Solve the inequality.<br> -5-x/3&lt;4
lora16 [44]
Hey there! :)

(-5 - x)/(3) < 4

Start out by multiplying both sides by 3. This is to get rid of any fractions we have!

3 • (-5 - x)/(3) < 4 • 3

Simplify!

-5 -x < 12

Add 5 to both sides so that we can isolate our variable.

-5 - x + 5 < 12 + 5

Simplify!

-x < 17

Divide both sides by -1.

Keep in mind that when dividing by a negative number, you must change the sign of the “crocodile mouth.” So, < turns into >.

-1 / -x > 17 / -1

Simplify.

x > -17

Hope this helped! :)
