B.
Because when doing the math, letter B fits the criteria of a quadratic equation. Which is ax^2 + bx + c = 0.
A is wrong because if we were to do the math, there would be no ax^2. The most important thing in a quadratic equation is the term ax^2, bx and c do not matter as much.
C is wrong because there cannot be a greater exponent than ^2.
D is wrong because of the same reason as letter a.
Cavalieri's principle states that if two solids of equal height have equal cross-sectional areas at every level parallel to the respective bases, then the two solids have equal volume.
So, the subtraction looks like this:
223
-119
_______
The reason why combining place values here is necessary is that 3 is less than 9 (so I can't just substract in the one's place without going to negative numbers)
so we combine the ones and tens places and substract the whole: 23-19 is four!
223
-119
_______
04
and then we continue
223
-119
_______
204
and that's the result!
Answer:
yes and no
Step-by-step explanation:
Thus, the ratios 6 : 8 and 12 : 16 are equal. Therefore, they form a proportion. Thus, the ratios 24 : 28 and 36 : 48 are unequal. Therefore, they do not form a proportion.
A=28.27 miles Sq
A= pie r2 = pie r.3 to 2nd power = 28.27 square miles
