Pretty sure the answer is k
Answer:
x +4
Step-by-step explanation:
The trinomial x² +8x +16 is a perfect square trinomial, so factors as ...
x² +8x +16 = (x +4)²
Assuming the side length is one of the factors of the given area, it will be ...
side length = (x +4)
Step-by-step explanation:
Scale factor of STUV to S'T'U'V
= Length of T'U' / Length of TU
= 6/12 = 0.5.
Let the price of 1 litre of milk be x$
Let the price of 1 loaf of bread be y$
According to the problem
333x + 555y =11
444x+444y=10
On subtracting the two,
We get
(333x+555y=11) * 444
(444x+444y= 10) * 333
(-) (-) (-)
147852x + 246420y =4884
147852x + 147852y = 3330
(-) (-) (-)
------------------------------
98568y = 1554
y = 1554/98568
= 0.0157$
=0.02$
Price of 1 loaf of bread= 2 cents
On putting the value of y
333x + 555*0.0157 = 11333x + 8.7135 = 11333x = 2.2865x = 2.2865/333x = 0.00068$ = 0.01$
Price of 1 litre of milk = 1 cent

1985year ->275cell phones->100%
1994year -> x cell phones ->100%+360%
40% • (1994-1985)= 40% • 9= 360%
275 cell phone 100%
X cell phones. 100+360%=460%
x=275•460%/100%
x=12420/100
x=1265
99% sure this is a correct answer
x=275 • 460%/100%
x=12,420/100
x=1265
1994-1985= 9 yrs • 40%= 360%
