Answer:
(15x- 20) x squared
Step-by-step explanation:

and also

now, we know that V varies directly to T and inversely to P simultaneously
thus

so
Answer:
Step-by-step explanation:
x/70=0.5/20
x=35/20
x=1.75
Ann will need 1.75 cups of sugar.
Given:
x = 12 in, y = 16 in and z = 20 in
To find:
The surface area of the geometric shape.
Solution:
Area of top rectangle = z × z
= 20 × 20
Area of top rectangle = 400 in²
Area of middle rectangle = z × y
= 20 × 16
Area of middle rectangle = 320 in²
Area of bottom rectangle = z × x
= 20 × 12
Area of bottom rectangle = 240 in²
Area of left triangle = 

Area of left triangle = 96 in²
Area of right triangle = 

Area of right triangle = 96 in²
Surface area = 400 + 320 + 240 + 96 + 96
= 1152
The surface area of the geometric shape is 1152 in².
