Answer:

D

Step-by-step explanation:

Break it into 2 parts.

First Part

4s (5s^2 + 10s + 3)

20s^3 + 40s^2 + 12s

Second Part

2 (5s^2 + 10s + 3)

10 s^2 + 20s + 6

Now add the like terms

20s^3 + (40s^2 + 10s^2) + (12s + 20s) + 3

20s^3 + 50s^2 + 32s + 6

Three times a larger number is 30 more than 5 times a smaller number. The sum of the larger number and 5 times the smaller numbe

slava [35]

3y = 5x + 30

y + 5x = 50 .......(1)

3y - 5x = 30 .....(2) - rearranging the first equation.

Add (1) and (2):-

4y = 80

y = 20
Now plug y = 20 into equation (1):-
20 + 5x = 50
5x = 30
x = 6

The 2 numbers are 6 and 20.

Please solve this fast

Korolek [52]

Step-by-step explanation:

1.

$qr - pr \: + qs - ps$

$r(q - p) + s(q - p)$

$(r + s)(q - p)$

2.

${x}^{2} + y - xy - x$

${x}^{2} - x - xy + y$

$x(x - 1) - y(x - 1)$

3.

$6xy + 6 - 9y - 4x$

$- 4x + 6 + 6xy - 9y$

$2( - 2x + 3) - 3y( - 2x + 3)$

$(2 - 3y)( - 2x + 3)$

4.

${x}^{2} - 2ax - 2ab + bx$

$x(x - 2a) - b(x - 2a)$

$-(x +b)(2a-x)$

5.

$axy + bcxy - az - bcz$

$xy(a + bc) - z(a + bc)$

$(xy - z)(a + bc)$
