Answer:
7 millimeters
Step-by-step explanation:
Volume is the area of the base times it's length.
140/10 is 14
so the area of the triangle is 14
the formula for area of a triangle is base times height divided by 2
so
d x 4/ 2 = 14
multiply both sides by 2
d x 4 = 28
divide both sides by 4
d=7
I think it 48 i’m not sure
...it’s 0.21 because 21% is 21/100 which makes it 0.21
This is what I got pls mark me brainlest
subtract 6 from the 21x+6. Then divide by 21. The answer is going to be -6/21
