multiplication is for example 10×500=5,000
division is for example 5,000÷10=500
BC is greater than AC is correct. If you need help with the construction, feel free to ask.
And maybe you're not clear with the options, because you've written BC two times which is necessarily not an answer/option.
X=real height of the tree
1 cm / 0.75 m=6.5 cm / x
x*1cm=0.75 m*6.5 cm
x=(0.75 m*6.5 cm) / 1 cm=4.875 m
therefore: the real height of a tree is 4.875 m,
Answer:
f(x)=-5x+1x=−5x+1, find f(6)
f(6)= -5(6)+1(6)=-5(6)+1
F(6)=-24,-29
