Answer:
x = 
Step-by-step explanation:
Given
- 24x - 15 = - 27 ( add 15 to both sides )
- 24x = - 12 ( divide both sides by - 24 )
x =
= 
n ∈ natural even numbers
Step-by-step explanation:
1 + 3 + 5 + 7 + … + (2n-1)
sum of the first n terms :
Sₙ = n/2(a + Uₙ)
Sₙ = n/2(1 + 2n - 1)
Sₙ = n/2(2n)
Sₙ = n²
∴ so, the solution of n is all natural even numbers
Answer:
width of rectangle is 87
Step-by-step explanation:
because perimeter of rectangle = 2(l+w)
Usually, we use the slope formula to find the slope of a line when we know two points on the line. But if we already know the slope of a line, we can use the slope formula to find a missing coordinate of a point on the line.
