The equation that best models this situation would be: y=40+30x
Answer:
(x+6) feet, 110sq ft
Step-by-step explanation:
Area = width * length = something * (x + 7)
Width = (x+6) as 6 and 7 add to 13 and times to 42.
To confirm expand (x+6)(x+7)=x^2+6x+7x+42=x^2+13x+42
(x+6) feet
4^2+13(4)+42=16+52+42=110 sqft
60 cm 3 is the volume of that cuboid
I <em />cant see what the numbers are but to find a cube, you do the number times itself 3 times example: 3 x 3 x 3 = 27. For cubing you do the number times itself twice for example 3 x 3 = 9.
I can see the square root though.
G: 36 = 6 64 = 8 81 = 9 25 = 5 324 = 18 529 = 23
The rest you should be able to understand with the explaining. Square root is finding what multiplied by itself is that number. Cube root is what times itself 3 times is that number. Hope this helps.
