As we know that the area of a rectangle is -
length × Breadth
So, here length = (3n+1)
Breadth = (2n-5)
Area of rectangle
= (3n+1)(2n-5)
= 3n(2n-5)+1(2n-5)
= 6n² - 15n + 2n - 5
= 6n² - 13n - 5
Answer) Area of rectangle is 6n² - 13n - 5

Step-by-step explanation:
Answer:
x and EAF are 27 degrees
Step-by-step explanation:
Since GAF is a right angle as indicated by the little square, GAC and CAF must add up to 90 degrees. Therefore, x is 90-63=27 degrees. The situation is the same for angle EAF. Hope this helps!
Answer:
√18 = 3√2
Step-by-step explanation:
the square root of 18 = √18
18;
1 × 18 = 18
2 × 9 = 18
3 × 6 = 18
6 × 3 = 18
9 × 2 = 18
18 × 1 = 18
9 has a perfect square
So,
√18 = √(2*9)
= √2 * √9
= 3√2
√18 = 3√2
Perfect square
1 × 1 = 1
2 × 2 = 4
3 × 3 = 9
4 × 4 = 16
5 × 5 = 25
Therefore,
√18 is between 4 and 5
