Answer:
m = - 2.27 or m = 16.27
Step-by-step explanation:
Given
m² - 14m - 37 = 0 ( add 37 to both sides )
m² - 14m = 37
To complete the square
add ( half the coefficient of the m- term )² to both sides
m² + 2(- 7)m + 49 = 37 + 49, that is
(m - 7)² = 86 ( take the square root of both sides )
m - 7 = ± 
( add 7 to both sides )
m = 7 ± , that is
m = 7 - ≈ - 2.27 or m = 7 + ≈ 16.27

Answer:
Perimeter = 9700 cm
Step-by-step explanation:
Dimensions of sides are;
12, 2x, 12, 5, 5, circumference of semi circle
Now, the semi circle has a radius of 7. Thus, the diameter = 7 × 2 = 14
We see that x is the diameter. Thus, x = 14
Thus; base of trapezium that is 2x = 2 × 14 = 28
Also, circumference of semi circle = 2πr = 2π × 7 = 44
Thus;
Perimeter of shape = 12 + 2(14) + 12 + 5 + 5 + 44
Perimeter = 97 m
Converting to cm, we multiply by 100 to get;
Perimeter = 97 × 100 cm
Perimeter = 9700 cm
Hello from MrBillDoesMath!
Answer: 1/2
Discussion:
Note that:
16 /2 = 8 (the next term in the sequence)
8 /2 = 4 (the next term in the sequence)
4 /2 = 2 (the next term in the sequence)
We are repeatedly multiplying by 1/2
Thank you,
MrB
