Answer:
A
Step-by-step explanation:
given
16x² + 16xy + 4y²
an expression factorised as a perfect square has the form
(ax + by)²
= a²x² + 2abxy + b²y²
16x² + 16xy + 4y² ← is in this form
with a² = 16 , b² = 4
so a = = 4 and b = = 2
then 2ab = 2(4)(2) = 16
Thus
16x² + 16xy + 4y² = (4x + 2y)² ← in factorised form
B. y = -3(x + 3)2 - 6
C. y = -3(x - 3)2 + 6
D. y = -3(x - 3)2 - 6
Which algebraic expression could Jonah use to find the value of the items?
A.
2b
B.
b • b
C.
b + d
D.
the improper fraction is 27/7
To convert the mixed number 3 6/7 to an improper fraction, we need to combine the whole number part with the fractional part.
First, multiply the whole number (3) by the denominator (7), which gives us 21. Then, add the numerator (6) to get 27.
Next, write the sum (27) as the numerator and keep the denominator (7) the same. The resulting improper fraction is 27/7.
This means that there are 27 parts (numerator) out of 7 equal parts (denominator). The improper fraction emphasizes the total number of parts beyond a whole number.
Converting the mixed number 3 6/7 to the improper fraction 27/7 allows for easier mathematical operations and comparisons with other fractions.
Therefore, the improper fraction is 27/7
