Answer:
32 256 cubic inches
18.7 cubic feet
Step-by-step explanation:
4 feet = 4 × 12 = 48 inches
8 feet = 8 × 12 = 96 inches
7 inches = 7 ÷ 12 = 0.583 feet
Volume = length × width × height
V = 48 × 96 × 7 = 32 256 cubic inches
V = 4 × 8 × 0.583 = 18.7 cubic feet
Answer:
QR = 5
Step-by-step explanation:
Since the parallelograms are similar, then the ratios of corresponding sides are equal, that is
= 
, then
= 
( cross- multiply )
9QR = 45 ( divide both sides by 9 )
QR = 5
Since it's a square it must have 4 sides.
20÷4=5
area=l×w or b×h
5×5=25 (the sides of a square have the same length)
the area of the photograph is 25in²

Every whole number is a rational number because its a whole number meaning it's not a fraction becasue fractions are irrational numbers.
~ All whole numbers are rational but not all rational numbers are whole.
Hope this helps!!! :D
F(x) = 3x - 2
g(x) =2x + 1
(f-g)(x) = 3x - 2 - 2x -1 collect like terms.
= x - 3
