Answer:
3x^4 - 13x^3 - x^2 - 11x + 6.
Step-by-step explanation:
x^2-5x+2 x 3x^2 +2x +3
= x^2(3x^2 +2x +3) - 5x(3x^2 +2x +3) + 2(3x^2 +2x +3)
= 3x^4 + 2x^3 + 3x^2 - 15x^3 - 10x^2 - 15x + 6x^2 + 4x + 6
Adding like terms:
= 3x^4 - 13x^3 - x^2 - 11x + 6.
Answer: 1
Step-by-step explanation:
3x = 24 - 9
3x = 15
x = 15/3
x = 5
Answer: B) x= 5 or the second option.
I believe 5x(8+3) is equal to 40x + 15x meaning those two numbers are the whole numbers you are looking for.
Answer:
31.5 m^2
Step-by-step explanation:
To find the amount for 7 bags, create a proportion.

To solve for y, cross multiply numerator to denominator of each fraction.
4(y) = 18(7)
4y= 126
y= 31.5
7 bags will do 31.5 m^2
