Answer:
1. 3
Step-by-step explanation:
For the first one, you have to follow m(slope)=y2-y1/x2-x1.
So in this case for the first one, it's 4-(-2)/3-(1) which is 3.
Figure 1 is 50 cm. Figure 2 is 225 mm.
Quadratic expression
5x + 3x^2 − 7
Degree of expression = 2
So it is Quadratic expression
9 3/4 = 975%
