Step-by-step explanation:
7x(√x - 7√7) Multiply √7x to "√x" and "-7√7" respectively:
√7x*√x - 7√7*√7x
First is to simplify: √7x² - 7√7²x
Extract the squares: x√7 - 7*7√x
Then, we simplify: x√7 - 49√x
After simplifying the equation, I got the answer x√7 - 49√x.
The area of a triangle formal is base times height divided by 2. So 9x 12 which equals 108 then you divide that by 2 which equals 54 and the unit is cm^2
the ratio of apple juice to coconut milk to orange juice is:
45:100:20 = 9:20:4
Answer:
answer 2) 24
Step-by-step explanation:
after the dilation pt D is (8,-32)
after the dilation pt E is (-16,16)
if you use the distance formula for these two points you get 
which simplifies to 24
