Step-by-step explanation:

S=smaller number; L=larger number=3S

4S+5L=133

4S+5(3S)=133

4S+15S=133

19S=133

S=7 ANSWER 1: The smaller number is 7.

L=3S=3(7)=21 ANSWER 2: The larger number is 21.

CHECK:

4S+5L=133

4(7)+5(21)=133

28+105=133

133=133

Brut [27]

The area of rectangle with length l and width w is

$A=l\cdot w.$

If the length of rectangle is expressed as $l=3x^2 + 5x + 10$ and the width of rectangle is expressed as $w=x^2-3x-1$ , then the area of rectangle is

$A=(3x^2 + 5x + 10)(x^2-3x-1)=3x^4-4x^3-8x^2-35x-10.$
