Answer:

Step-by-step explanation:

Equation

12x + (8x + 5) + 15x = 180    All triangles have 180o for their interior angles.

12x + 8x + 5 + 15x = 180      Combine like terms on the left

35x + 5 = 180                        Subtract 5 from both sides

     <u>  - 5      -5</u>

35x =175                                Divide by 35

x = 5

It's not clear what you want. x = 5 is one possibility

12x = 60

15x = 75

8x+5=45

is another possiblity

Multiply and simplify. 2x4yx⋅6xy2z3
OLEGan [10]

Answer:

The given expression 2x^4yx \times 6xy^2z^3   on multiplying  is 12x^6y^3z^3

Step-by-step explanation:

Consider the given two expressions 2x^4yx and 6xy^2z^3

We have multiply both expressions,

2x^4yx \times 6xy^2z^3

To multiply two terms first multiply constant numbers that is 6 × 2 = 12

For x , y and z apply property of exponent,

x^a\cdot x^b=x^{a+b}

Then power of x together will be,

x^4\cdot x\cdot x=x^{4+1+1}=x^6

Similarly for y powers,

y \cdot y^2=y^{1+2}=y^3

Since first term do not have any expression for z so it will remain same.

Thus, the given expression  on multiplying become,

2x^4yx \times 6xy^2z^3 is 12x^6y^3z^3
