N + 1 = 4n - 3
-4n -4n
-3n + 1 = -3
-1 -1
-3n -4
-3 -3
n= 1.33
According to multiplication you can use repeated addition to get the same product of the given equation.
Ex: 5x2= 2+2+2+2+2 ( 5 groups of 2)
Both will give you same answer (10).
Hence 2 x 3/4 = 3/4 + 3/4
Answer:
131.88cm
Step-by-step explanation:
Implement the formula for circumference of a circle:
2×pi(3.14)×r, r= 21cm and pi is given as 3.14. Substitute your given values into the formula above:
2 × 3.14 × 21= 131.88cm to the nearest hundreth
Step-by-step explanation:
AB + BC = AC
50° + BC = 180°
BC = 180° - 50°
BC = 130°
AB = 50°
BC = 130°
AC = 180°
Answer:
A = 49 in^2
Step-by-step explanation:
The perimeter of a square is found by
P = 4s where s is the side length
28 = 4s
Divide each side by 4
28/4 = 4s/4
7 =s
We want to find the area
A = s^2 where s is the side length
A = 7^2
A = 7^2
A = 49 in^2
