Answer:
9x² + 6xy + y²
Step-by-step explanation:
(a + b)² = a² + 2ab + b²
a = 3x
b = y
(3x +y)² = (3x)² + 2*3x*y + y²
= 9x² + 6xy + y²
(3x)² = 3²*x² = 3*3*x² = 9x²
Answer: C
Step-by-step explanation:
It is C because you are adding money to something you already have, hence positive integer
23.67 million is equal to .02367 billion
Answer:
This approach often yields much more accurate results than the trapezoidal rule does. Again we divide the area under the curve into n equal parts, but for this rule n must be an even number because we're estimating the areas of regions of width 2Δx.
So, here is exactly how you would do this:
-3m-2e if m=6 and e=1
We know the values of e and m. We can plug these in to evaluate.
Simply replace the number 6 in place of m and 1 in place of e in -3m-2e
-3m-2e Original expression
-3(6)-2(1) With values plugged in
-18-2 Simplified
-20 Final answer
Our final answer would therefore be: -20
