16r^2+ 2r -4r
16r^2 - 2r
2r ( 8r -1)
Answer:
7/20
Step-by-step explanation:
GIven:
Battery A = 4/5 remaining
Battery B = 9/20 remaining
assuming both batteries are otherwise identical (except for charge level remaining), then,
Battery A - Battery B
= 4/5 - 9/20
we need to convert both fractions to same denominator to perform the subtraction easily. Note that the Least Common Multiple for 5 and 20 is 20, hence we convert both denominators to 20,
Battery A - Battery B
= 4/5 - 9/20
= (4/5) (4/4) - 9/20
= 16/20-9/20
= 7/20
Answer:
C = a² + 2ab + b²
Step-by-step explanation:
From the diagram above,
Let the dimension of the square be
A (length) = (a + b) and B (breadth) = (a + b).
Area of the square is A*B
A * B = (a + b) * (a + b)
Area = a² + ab + ab + b²
Area = a² + 2ab + b².
Therefore the expression that defines the area of the square is a² + 2ab + b².
Answer:
C) horizontal compression and reflection across the y-axis
Step-by-step explanation:
To quickly solve this problem, we can use a graphing tool or a calculator to plot the equation.
Please see the attached image below, to find more information about the graph
The original equation is:
f(x) = 2x
The new equation is:
f(-5x) = 2(-5x)
f(-5x) = -10*x
The answer is
C) horizontal compression and reflection across the y-axis
7/24 I hope this helps you
