Answer:
3x^{4} + 4x³ + 5x - 6
Step-by-step explanation:
Given in the question is an expression
(3x³ - 2x² + 4x - 3)(x + 2)
Apply distributive law
(3x³ - 2x² + 4x - 3)(x) + (2)(3x³ - 2x² + 4x - 3)
3
- 2x³ + 4x² -3x + 6x³ - 4x² + 8x - 6
Rearrange the like terms
3
+ x³(-2+6) +x²(4-4) +x(-3+8) - 6
3
+ 4x³ + 5x - 6
After performing indicated operation the result is

Area of a triangle is 1/2 of base *height
A=1/2 *10 and 6/7 *9 and 3/8
break the whole numbers: 1/2 *76/7 * 75/8 =1425/28
write it into mixed number:50 and 25/28
