Hi
k (a+b) = ka+kb
so : 8 (3x+4) = 8*3x +8*4 = 24x +32
Answer:
cross multiply
(8m)(11)=(6)(3)
88m=18
then divide by 88 on both sides
m=18/88 then reduce by 2 -----> 9/44
Step-by-step explanation:
Answer:
11.9 mm
Step-by-step explanation:
We can find d by applying the cosine rules.
d² = 21² + 27² - 2(21)(27) cos (25)
d² = 441 + 729 - 1027.75
d² = 142.25
d = √142.25
d = 11.9 mm (nearest tenth)
