Answer: x² - 15x + 56</h2>
<h3>
Step-by-step explanation:</h3>
To expand the brackets, each term in the first bracket must be multiplied by each term in the second bracket and then simplified:
(x-8) (x-7) = (x × x) - (7 × x) - (8 × x) + (8×7)
= x² - 7x - 8x + 56
= x² - 15x + 56
4 blue, 3 red
twice as many black pens as blue pens.....black pens = 2(4) = 8
so there are : (4 + 3 + 8) = 15 total pens
fraction of blue pens to total pens = 4/15
