Macy finished a job in 3/4 hours . James finished it in 4/5 of the time Macy took. How Long did James take to finish the job?

3/4 hours is equal to (60 minutes divided by 4) times three. [15*3 = 45]
Macy finished in 45 minutes. Now we have to find 4/5 of 45. So (45 divided by 5) times 4. [9*4 = 36]
See the pattern? So the answer for 45 minutes divided by 4/5 is 36 minutes.

Simplify the polynomial expression given below.<br><br> (2x − 1)(2x2 + 5x + 3) + (3x + 6)

fenix001 [56]

Answer:

$4x^{3}+8x^{2} +4x+3$

Step-by-step explanation:

Hello

To simplify the polynomial we must eliminate the parentheses

by definition

$ax^{n}*bx^{m} =abx^{n+m}$

$(2x-1)(2x^{2} +5x+3)+(3x+6)\\(4x^{3} +10x^{2} +6x-2x^{2} -5x-3)+(3x+6)\\\\We\ add\ the\ similar\ terms\\\\(4x^{3}+8x^{2} +x-3)+(3x+6)\\\\4x^{3}+8x^{2} +4x+3$
