Answer:
YES IT IS A PERFECT SQUARE
Step-by-step explanation:
equate the equation to zero
x^2+8x+16=0
c is the product while the coefficient of b is the sum
P=16
S=8
find a pair of numbers that the product is 16 and the sum is 8
the numbers are (4,4)
(x^2+4x) (4X+16)
ignore 8x and arrange as shown above
then bracket the equation
x(x+4)+4(x+4)
you simplify and remain with (x+4) (x+4)
having similar roots making it a perfect square

Answer:
<em>945 minutes.</em>
Step-by-step explanation:
<em>10% = 0,1</em>
<em>450 + 450 · 0,1 = 495 (minutes) - Oliver will read next month.</em>
<em>450 + 495 = 945 (minutes) - he read in all during the two months.</em>
A, because you follow the numbers and just put "is to" and "as" in the middle.
