Answer:
<h3> 63.25m</h3>
Step-by-step explanation:
The area of the square wall = L² where;
L is the length of the wall.
Given
Area of the mosaic = 4000m²
Substitute into the formula and get L
4000 = L²
Square root both sides
√4000 = √L²
√4000 = L
Rearrange
L = √4000
L = 63.25m (to the nearest hundredth)
<h3>Hence the length to the nearest hundredth is 63.25m</h3>
<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:
630/x+5 (remainder over divisor)
