Answer:
a,
b,
Step-by-step explanation:
Given
Solving (a): Books using 5 small and 7 large boxes;
This is calculated as follows
For Small box
For large box:
Solving (b): s small and l large
We use the same concept as (a) above:
For Small Box
For large box
The product of <span>2x^2+6x-8 and x+3 is:
= (</span><span>2x^2+6x-8)(x+3)
= 2x^3 + 6x^2 - 8x + 6x^2 + 18x - 24
= 2x^3 + 12x^2 + 10x - 24
This answer can still be simplified by dividing everything by 2
= x^3 + 6x^2 + 5x - 12
So the product of </span>2x^2+6x-8 and x+3 is equal to <span>x^3 + 6x^2 + 5x - 12.</span>
