Find the properties of the given parabola.
68 + a = 180
a = 180 - 68
a = 112
b = 2(112) - 104
b = 224 - 104
b = 120
answer

Answer:
PQ= <em><u>1</u></em><em><u>0</u></em>
Step-by-step explanation:
To find intersection of the line ,put y=0 in the equation,cuz points on x axis have ordinate equals to '0'
you have, y=2x+8 ; put y =0,to find it's intersection to x-axis
i.e, 0=2x+8
i.e, 2x= -8
i.e, x= -8/2
i.e, x= -4
Point P is (-4,0)
again, you have y=2x-12, put y=0
i.e,0= 2x-12
i.e, 2x=12
i.e, x=6
Point Q is (6,0)
now distance PQ is
√(6-(-4))^2 +(0-0)^2
i.e, √(10)^2
i.e, 10
distance btwn PQ is 10 unit!

The length of the 2D cross-section = 22cm
Breadth of 2D cross-section = 12cm
Since it's inside a rectangular prism, it's area will be given by the formula of area of a rectangle.
→ Area of 2D cross-section = 22×12 = 264 cm²
-2(-x + 3y) - 3(x - 5y)
-2(-x) - 2(3y) - 3(x) + 3(5y)
2x - 6y - 3x + 15y
2x - 3x - 6y + 15y
-x + 9y
