Answer:
A. 35
Step-by-step explanation:
a || b .....(given)
line c is their transversal.
-> x° + (3x + 40)° = 180° (Interior angles on the same side of transversal)
-> (3x + 40 + x)° = 180°
-> (4x + 40)° = 180°
-> 4x + 40 = 180
-> 4x = 180 - 40
-> 4x = 140
-> x = 140/4
-> x = 35
Answer:
x equals plus or minus square root of 5 minus 1
Step-by-step explanation:
we have
Divide by 2 the coefficient of the x-term
squared the number
Adds both sides
Rewrite as perfect squares
take the square root both sides
therefore
x equals plus or minus square root of 5 minus 1
Answer:
The answer is 72 inches in 24 hours.
Step-by-step explanation:

Answer:
The length of the rectangle is 18 cm
The width of the rectangle is 6 cm
Step-by-step explanation:
Let
x-----> the length of the rectangle
y----> the width of the rectangle
we know that
The perimeter of the rectangle is
we have
so
------> equation A
------> equation B
Substitute equation B in equation A and solve for y
48=2(2y+6+y)
48=2(3y+6)
48=6y+12
6y=48-12
y=36/6=6 cm
Find the value of x
x=2(6)+6=18 cm
The area of the rectangle is
A=xy
A=18*6
A=108 cm^2
