Answer:
24
Step-by-step explanation:
It is done by Middle term splitting.
Taking the general equation ax² + bx + c, by middle term splitting, "b" should be splitted such that the numbers either on adding or on subtracting must be equal to "b" and their products must be equal to "a x c".
For example, in the question it's already given that the equation 8x² + bx + c is middle term splitted into 8x² + px + qx + 3.
So, that means "p x q" must be equal to "8 x 3", i.e., 24.

Answer:
40/21
Step-by-step explanation:
-4/7+(-4/3)
common factor is 21
=21/7×-4-21/3×4
=3×-4-7×4 all divided by 21
=-12-28 all divided by 21
=40/21
Step-by-step explanation:
so he already down 20 ft so he ascends (goes up) 9 feet, so hes at 11 feet right now. then he descends 12 (goes down) feet so hes at 23 feet. lastly he ascends 15 feet (goes up) more. so the answer is 8
