Question

11. Length of rectangle is (x+3), and its breadth is (10+x) units then its polynomial function is
​

Answer 1

Answer:

(X+3)(10+X)

X(10+x) + 3(10+x)

10x +x² +30+3x

x²-13x+30

Answer 2

Answer:

X^2 + 13X + 30

Step-by-step explanation:

Length =(X+3)

Breadth =(10+x)

(X+3) (10+X)

X(10+X) +3(10+X)

10X + X^2 + 30 + 3X

X^2 + 13X +30
