Answer:
20cm
Step-by-step explanation:
Frame L&W: 25×20
PictureL&W:20×16
25-20=5
Length of Picture frame=5
Length of Picture frame=4
5×4=20cm²
To find area you multiply length by width
F(x) = (x - 3)(x - 7)
expanding the brackets gives:
f(x) = x^2 - 10x + 21

Answer:
y = 5x - 5
Step-by-step explanation:
It appears that the graph intersects the y-axis at (0, -5). This point is the y-intercept of the line.
As we move from (0, -5) to the point (2, 5), x increases by 2 and y increases by 10. Thus, the slope of the line through these two points is
m = rise / run = 10 / 2 = 5.
The slope-intercept form of the equation of a straight line, y = mx + b, becomes y = 5x - 5
