Ratio :
Width : Length
3 : 5
Let the factor be x
(3x)(5x) = 15x²
15x² = 135
x² = 9
x = √9
x = 3
Width = 3 x 3 = 9 cm
Length = 3 x5 = 15 cm
Answer: The dimension is 9cm by 15 cm
Answer in simplest radical form would be 7.(:
Answer:
(0, - 3.5 )
Step-by-step explanation:
Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is
[ (x₁ + x₂ ), (y₁ + y₂ ) ]
Here (x₁, y₁ ) = A(- 5, - 4) and (x₂, y₂ ) = B(5, - 3)
midpoint = [ (- 5 + 5), (- 4 - 3 ) ] = ( (0), (- 7) ) = (0, - 3.5 )
Adding 6 to both sides and taking the square root, remember that x can be the poitivie and negative root
x^2-6=0
add 6
x^2=6
squaer root both sides
x=√6
x=+√6 and -√6
