Use distribution to find the answer to this one.

5x * 6x² = 30x^3

5x * 3x = 15x²

5x * 7 = 35x

-1 * 6x² = -6x²

-1 * 3x = -3x

-1 * 7 = -7

30x^3 + 15x² + 35x - 6x² - 3x - 7 → simplify this using like terms (look at the exponent of x and if there even is one)

30x^3 stays becuase there is no other like terms

15x² - 6x² = 9x² becuase they are like terms

35x - 3x = 32x because they are like terms

-7 stays because ther is no other like terms

Put these together in the final answer: 30x^3 + 9x² + 32x - 7

Hope this helps!

The three angles in a triangle are in the ratio 3:4:5. Find the angles
insens350 [35]
The angles are 45° 60° and 75°

Elaboration:
Let the three angles be 3x 4x and 5x
( since the sum of interior angles of triangle=180° )
3x+4x+5x= 180
12x = 180
x = 15
3x= 45
4x= 60
5x= 75
