<u>Answer:</u>
x² - 10x + 25
<u>Step-by-step explanation:</u>
The formula for squaring any binomial (an expression with two terms) is:
(a ± b)² = a² ± 2ab + b²
Let a = x and b = 5.
∴ Substituting:
(x - 5)² = x² - 2(x)(5) + (-5)²
= x² - 10x + 25

Answer:
Diameter of the can = 18 Cm
Step-by-step explanation:
Given:
Curved surface of cylindrical can = 162
Height of cylindrical can = 9 Cm
Find:
Diameter of the can = ?
Computation:
Curved surface of cylindrical can = 2rh
Diameter of the can = 2×r
Diameter of the can = 2×9 Cm
Diameter of the can = 18 Cm
Answer:
24
Step-by-step explanation:
We are solving for variation (without repitition)
n = 4 digits (6,7,8,9)
p = 3 digits no.
variation = nfactorial/ (n-p) factorial.
4x3x2x1/(4-3)factorial = 24/1
= 24.
there are 24 3-digit number you can select from 6,7,8,9 without having a recurring number.
