The area of a square can be found by squaring the side length. So, the area of the picture can be found by multiplying 16 by 16. 16 x 16 is 256.
Answer:
Step-by-step explanation:
Using the slope formula (y2-y1)/(x2-x1), we get (0 - (-2)/(2-0). Simplified, this gets you (0+2)/(2-0). This is equal to 1, which means the slope is one. Putting this into slope-intercept form (y=mx+b), we can plug in (0, -2), getting us -2=0+b. b is equal to -2 then. Thus, the full equation would be y=x-2
y = x² - 4x + 8
4x + y = 12
4x + y = 12
4x + (x² - 4x + 8) = 12
x² + 4x - 4x + 8 = 12
x² + 8 = 12
- 8 - 8
x² = 4
x = ±2
4x + y = 12
4(2) + y = 12
8 + y = 12
- 8 - 8
y = 4
4x + y = 12
4(-2) + y = 12
-8 + y = 12
+ 8 + 8
y = 20
(x, y) = (2, 4) and (-2, 20)
