Answer:
x²+8x+16
Step-by-step explanation:
f(x) = (x+4)²
= (x+4)(x+4)
= x² + 4x + 4x + 16
= x² + 8x + 16
We will start by adding 3x to both sides. This changes the equation to 6y=3x-6.
We then divide the entire equation by 6 to get y by itself. That leaves us with y=3/6x-1 which simplifies down to y=1/2x-1
It's 10.4 because you divide 272.48 by 26.2 and get 10.4
Answer:
y = -9x + 14
Step-by-step explanation:
y + 4 = -9 (x -2)
y + 4 = -9x +18
y = -9x + 14
Answer:
Base = 16, height 64
Step-by-step explanation:
It's a triangle so u have to multiply it with 1/2 or divide by 2, x will equal both height and base:
(1/2)4x^2 = 512
Multiply 2 to both sides
4x^2 = 1024
divide both sides by 4
x^2 = 256
= 
x = 16, base is 16 and height is 16(4) = 64
Alright this took me some time but I got it now, u might think why 16 and 64? 16 times 64 is not 512, but the equation for a triangles area is
or b·h·1/2 , so if u plug the numbers into the equation it will equal 512:
16 · 64 · 1/2= 1024 · 1/2 = 512
