Expand. Your answer should be a polynomial in standard form. 3x(x to the second power, -5x+6)

3x³ - 15x² + 18x

Step-by-step explanation:

Given

3x(x² - 5x + 6) ← distribute the parenthesis by 3x

= 3x³ - 15x² + 18x ← in standard form

93.8

step-by-step explanation:

lets say, first number = x

second number = 3x+7

total = 49

(x)+(3x+7)= 49

4x+7 = 49

4x = 42

x = 42/4

x= 10.5

x= 10.5

3x+7 = 3(10.5)+7 = 93.8
