The sum of two polynomials is 8d5 – 3c3d2 5c2d3 – 4cd4 9. if one addend is 2d5 – c3d2 8cd4 1, what is the other addend? 6d5 – 2c
statuscvo [17]

The sum of two polynomials is 8d^5 - 3c^3d2 +5c^2d^3 - 4cd^4 +9

2d^5 - c^3d^2 +8cd^4 +1 would be 6d^5 - 2c^3d^2+ 5c^2d^3 - 12cd^4 +8.

<h3>What are polynomials?</h3>

Polynomials are those algebraic expressions that consist of variables, coefficients, and constants. The standard form of polynomials has mathematical operations such as addition, subtraction, and multiplication.

Given that

8d^5 - 3c^3d2 +5c^2d^3 - 4cd^4 +9\\

Now

if one is added i.e.

2d^5 - c^3d^2 +8cd^4 +1,

Now let us assume the other polynomial be x

So,

8d^5 - 3c^3d2 +5c^2d^3 - 4cd^4 +9\\ = x + 2d^5 - c^3d^2 +8cd^4 +1,

x = 8d^5 - 3c^3d2 +5c^2d^3 - 4cd^4 +9\\ - ( 2d^5 - c^3d^2 +8cd^4 +1,)

x = 6d^5 - 2c^3d^2+ 5c^2d^3 - 12cd^4 +8

What is the measurement of B in this picture
trapecia [35]

Step-by-step explanation:

angle A = angle B. ( corresponding angles of two parallel lines)

8x-8°=5x+25°

8x-5x= 25°+8°

3x=33°

x=11°

angle B= 5x+25°

= 5(11)°+25°

= 55°+25°

= 80°
