The two numbers are (7+√37)/2 and (7-√37)/2.
(7+√37)/2+ (7-√37)/2= 7
[(7+√37)/2]* [(7-√37)/2]= 3
Hope this helps~
23.60/5 = $4.72 per bag
32.76/7 = $4.68 per bag
so 7 bags of apples for $32.76
Answer:
Step-by-step explanation:
The first statement is correct. The volume of this rectangular prism is v = l*w*h, and so 495 cm^3 = (12*2.5 cm^2)*h is correct.
To find h, Zoe should divide 495 cm^3 by (12*2.5 cm^2), so the second statement is wrong.
The third statement is incorrect, due to an arithmetic error. 495 cm^3 divided by (12*2.5 cm^2) is 16.5 cm, not 15.5 cm. Thus: the missing height, h, is 16.5 c.m.

Step-by-step explanation:
A 3D figure is given to us and we need to find the Total Surface area of the 3D figure . So ,
From the cuboid we can see that there are 5 squares in one row on the front face . And there are two rows. So the number of squares on the front face will be 5*2 = 10 .
We know the area of square as ,
Hence the area of 10 squares will be 10x² , where x is the side length of each square. Similarly there are 10 squares at the back . Hence their area will be 10x² .
Also there are in total 12 squares sideways 6 on each sides . So their surface area will be 12x² . Hence the total surface area in terms of side of square will be ,
Now let's find out the TSA in terms of side . So here the lenght of the cuboid is equal to the sum of one of the sides of 5 squares .
Hence the TSA of cuboid in terms of lenght and breadth is :-
