Step-by-step explanation:
so let's first double the values
12 +12+ 2x-3+2x-3, combine values, we get 4x + 18
lets flip 18 to other side 4x =-18 , we get x =4.5
Answer: 4,772.8 cm2
Step-by-step explanation:
Hi, to answer this question we have to calculate measures of the rectangular label:
The width of the label is equal to the height of the can (8 cm), and the length is equal to the perimeter of the top or bottom of the can.
Perimeter of a circle (circumference): 2 π radius
Replacing with the values given:
C = 2 (3.14) 5 = 31.4 cm
So, the area of one label is:
Area of a rectangle: length x width = 31.4 x 8 = 251.2 cm2
Multiplying for the number of labels (19)
251.2 x 19 = 4,772.8 cm2

A) √50 = √(25 x 2) =√(5² x 2) = 5√2, what Jacklyn did is the other way round, instead of putting the perfect square out of the radical & keep the 2 inside, she inversed the sens of the operation
b) We have to find the square of the smaller & largest numbers that are near 50:
7² = 49 & 8² = 64==> so 49<50<64 & the number is between the square root of 7 & the square root of 8, but we also notice that 50 is very very near 49, hence let's try 7.1==> 7² = 7.1 x 7.1 = 50.41, which is a very good approximation. Then the approx. to √50 ≈ 50.41
