Answer:

Option (3) is correct.

-27x^9+y^6 is the expression written as the sum of cubes as

(-3x^3)^3+(y^2)^3

Step-by-step explanation:

<u>Sum of cubes</u> : is defined as  a^3+b^3

We have to choose a sum of cubes from given expressions,

Consider -27x^9+y^6

Here  -27x^9 can be written as (-3x^3)^3

and y^6 can be written as (y^2)^3

Thus, -27x^9+y^6=(-3x^3)^3+(y^2)^3

Hence, -27x^9+y^6 is the expression written as the sum of cubes as (-3x^3)^3+(y^2)^3

Thus, option (3) is correct.

PLS HELP!!!!! ASAP 7TH GRADE MATH<br> ILL MARK BRAINLIEST
Pani-rosa [81]

Answer:

Answer Below

Step-by-step explanation:

For a triangle the area is calculated using the formula: Area = half of base by altitude. A = 0.5 X b X a.

So to calculate the volume of a triangular prism, the formula is: V = 0.5 X b X a X h.

You can also search "how to find the volume of a triangular prism" and there will be a base calculator so u can figure out this problem!

Answer:

Step-by-step explanation:

Use Pythagorean theorem.

Hypotenuse² = base² + altitude²

5)  x²  = 12² + 6²

         = 144 + 36

  x²  = 180

x = √180

x = 13.42 ft

6) 25² = x² + 19²

625 = x² + 361

625 - 361 = x²

x² = 264

x = √264

x = 16.25 m

7)  x² = 7² + 576

        = 49 + 576

        = 625

x = √625

x = 25 in

8)  2.5² = 2²+ x²

6.25 = 4 + x²

6.25 - 4 = x²

x² = 2.25

x = √2.25

x = 1.5 yd
