=3÷8+1÷8-(14÷8)
=3÷8+1÷8-14÷8
=(3+1-14)÷8
=-10÷8
=-5÷4
=-1.25
Answer:
-3x^2
Step-by-step explanation:
46 because if the age of the son was 8 then the father was 24 and if we add 8 (because that’s how many years passed) we get 16 and 32 which fit the criteria so if we take off 1 year on each (because only 7 years pass instead of 8) we can add them together and get 46
Answer: 23.75
Step-by-step explanation:
475*.05=23.75
The expression that represents the approximate length of BC is; A: (3) sin(66)/sin (38)
<h3>Trigonometric Ratios</h3>
From the given triangle ABC, we see that;
∠A = 66°
∠C = 38°
AB = 3
Thus using sine rule, we have;
AB/sin C = BC/sin A
3/sin 38 = BC/sin 66
BC = (3sin 66)/sin 38
BC = 4.45
