Answer:
17n+9 feet
Step-by-step explanation:
The perimeter of a rectangle is twice the sum of length and width.
P = 2(L +W)
P = 2((4.5n +9) +(4n -4.5)) = 2(8.5n +4.5)
P = 17n +9
The perimeter of the rectangle is 17n +9 feet.
Answer:
theta = 180 -(A +B)
Step-by-step explanation:
The sum of the angles of a triangle is 180
theta + A + B = 180
solve for theta
Subtract ( A + B) from each side
theta +A+B -(A +B) = 180 -(A +B)
theta = 180 -(A +B)
Answer:
104
Step-by-step explanation:
2x^2+8x−5=0
This is written in the form
ax^2 + bx+c
a =2 b = 8 c=-5
The discriminant is
b^2 -4ac
8^2 - 4(2)(-5)
64 + 40
104
The discriminant is 104
