Answer:
x² - 16
Step-by-step explanation:
Use the FOIL method here where
F = first
O = outer
I = inner
L = last
F = x * x = x²
O = -4 * x = -4x
I = 4 * x = 4x
L = -4 * 4 = -16
Combine the terms to get x² - 16.
Answer:
d) 54 ft = 1645.92 cm
Step-by-step explanation:
Given : 54 ft.
To find : Approximately how many centimeters are in 54 ft.
Solution : We have given 54 ft.
We know
1 ft = 30.48 cm .
54 ft = 54 * 30.48 cm.
54 ft = 1645.92 cm.
Therefore, d) 54 ft = 1645.92 cm.
10x - 35 = 15x - 10
-35 = 5x -10
-25 = 5x
-5 = x
The value of x is -5.
assuming 
Then the column values for base five here are
5³ 5²

We can get 1 × 5³ = 125 → 219 - 125 = 94
We can get 3 × 5² = 75 → 94 - 75 = 19
We can get 3 x
→ 19 - 15 = 4
and 4 = 4 × 
Thus
= 
As a check
(1 × 125 ) + (3 × 25 ) + (3 × 5 ) + 4 = 219
