Answer:
C
Step-by-step explanation:
49x² + 28xy + 4y² ← is a perfect square of the form
(ax + by)² = a²x² + 2abxy + b²y²
49 = 7² ⇒ a = 7 and 4 = 2² ⇒ b = 2
2ab = 2 × 7 × 2 = 28
Hence
49x² + 28xy + 4y² = (7x + 2y)²
with factor 7x + 2y ⇒ C
Answer:
46.1 in
Step-by-step explanation:
Given data
Width= 30in
Height= 35in
To find the diagonal, we have to use the Pythagoras theorem
z^2= x^2+y^2
z^2= 30^2+ 35^2
z^2= 900+1225
z^2= 2125
z= √2125
z= 46.09
Hence the diagonal of the TV is 46.1 in
Answer:
522
Step-by-step explanation:
516 divided by 9 is 57.34
she would need 522 pennies and she would end up with 9 stacks of 58 pennies
The domain is the numbers you can use for x
so the domain is 4
the range is the possible y values we get from that domain
we get all real numbers because it goes up and down infinitey
domain is 4
range is all real numbers
11. As the number 11 there is only extended. If it is wrong, don't come blaming me!!
