No you can not simplify 5 over 36 you can immediately tell if it can be simplified by looking to see if it is a multiple in this case 5 is not a multiple of 36.

Let n be the first even number.
So the four consecutive even numbers are:
● n
● n+2
● n+4
●n+6
The smallest minus twice the larger is 4
● n-2(n+6)= 4
●n-2n-12 =4
● -n -12 =4
● -12 = 4+n
● -12-4 = n
● -16 = n
so the first even number is -16 and the largest one is -10
● -16+6= -10

Let m be the first integer
So the five consecutive integers are:
● m
● m+1
● m+2
● m+3
● m+4
The sum of this terms is 5.5 times the middle(m+2)
● m+m+1+m+2+m+3+m+4 = 5.5(m+2)
● 5m + 10 = 5.5 m +11
● -0.5 m = 1
●-m = 2
● m= -2
So the integers are;
● -2
● -1 (-2+1)
● 0
● 1
● 2
Answer:
Step-by-step explanation:
Solve for x over the real numbers:
x² + 14x + 38 = 0
Subtract 38 from both sides:
x² + 14x + 38 - 38 = 0 - 38
x² + 14x = -38
Add 49 to both sides:
x² + 14x + 49 = 49 - 38
x² + 14x + 49 = 11
Write the left hand side as a square:
x² + 7x + 7x + 49 = 11
x(x + 7) + 7(x + 7) = 11
(x + 7)(x + 7) = 11
(x + 7)² = 11
Take the square root of both sides:
Subtract 7 from both sides:
Step-by-step explanation:
1. In the picture down below.
2. Because they are = 20
100 ÷ 5 = 20
10 ÷ 0.5 = 10 x 2 = 20
1 ÷ 0.05 = 1 x 20 = 20
