Y = –x2 + 4x + 12
y = –3x + 24
so
–x2 + 4x + 12 = –3x + 24
x^2 -7x + 12 = 0
(x - 4)(x - 3) = 0
x - 4 =0; x =4
x - 3 = 0; x= 3
y = –3x + 24 = -3(3) + 24 = -9+24 = 15 (when x = 3)
y = –3x + 24 = -3(4) + 24 = -12+24 = 12 (when x = 4)
answer
(3, 15) and (4, 12)
No.
The perimeter is the distance all the way around the triangle.
So it's the sum of the lengths of the three sides.
The sum of three numbers doesn't depend on what order you
add them ... I think that's the 'commutative' property of addition.
So it doesn't matter which side you start with, or even what order
the sides are arranged in. The perimeter is always the same.
You have little to no information here but i assume you are using the apex program and the only spiral i know of is made up of 45 right triangles if you have more information im glad to help sorry dude
4.5 times 2.2 = 9.9
15.5-9.9= 5.6
5.6/3 can be written as 1 and 13/15
