Question 6: $38.82
question 7: t=5w
question 8: which blood type does the leaf number of people have
Abd is a right angled triangle so by pythagoras we know
and to calculate h we need to use the sine rule
i hope this helps
2b 2a
----------------- + -----------------
(b+a)^2 (b^2 - a^2)
2b 2a
= ----------------- + -------------------
(b+a)(b+a) (b+a)(b-a)
2b(b - a) + 2a(b + a)
= ------------------------------------
(b+a)(b+a)(b-a)
2b^2 - 2ab + 2ab + 2a^2
= ---------------------------------------
(b+a)(b+a)(b-a)
2b^2 + 2a^2
= ------------------------
(b+a)(b+a)(b-a)
2(b^2 + a^2)
= ------------------------
(b+a)^2 (b-a)
Answer:
Numerator: 2(b^2 + a^2)
Denominator: (b+a)^2 (b-a)
since parallel lines have the same slope, If the slope of AB is -3 then the slope of CD will also be -3
The answer to the question is d
