Answer:
sum of the polynomials is 
Step-by-step explanation:
Given polynomial is (7 x^3– 4 x^2) + (2 x^3 +3 x)
adding x^3 terms, now we get


Therefore the sum of given polynomial is

All you have to do is to move the decimal point 1 place to the right and then append E1 to the result:
0.770000 = <span>7.70000E1</span>
If you have line on the scatter plot that is drawn through the points (1,3) and (9,11) then we will first calculate the slope:
m=(y2-y1)/(x2-x1)=(11-3)/(9-1) = 8/8 = 1
Then the interception with y-axis:
y=mx+b
3= 1*1 + b
3-1=b
b=2
The equation is:
y=x+2

Step-by-step explanation:
Answer:
∠APB = 106°
Step-by-step explanation:
Method 1: Focus on Triangle APB
Every angle of equilateral triangle ABC is 60°
∠BAP = 60°
∠ABP = 60° - 46° = 14°
Total degrees in one triangle is 180°
∠APB = 180° - 60° - 14° = 106°
Method 2: Exterior Angle Theorm
∠APB = ∠PBC + ∠PCB
∠APB = 46° + 60°
∠APB = 106°
