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 – 2c3d2 5c2d3 – 12cd4 8 6d5 – 4c3d2 3c2d3 – 4cd4 8 6d5 – 4c3d2 5c2d3 – 12cd4 8 6d5 – 2c3d2 – 3c2d3 – 4cd4 8
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.
What are polynomials?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
[tex]8d^5 - 3c^3d2 +5c^2d^3 - 4cd^4 +9\\[/tex]
Now
if one is added i.e.
[tex]2d^5 - c^3d^2 +8cd^4 +1,[/tex]
Now let us assume the other polynomial be x
So,
[tex]8d^5 - 3c^3d2 +5c^2d^3 - 4cd^4 +9\\[/tex] = x + [tex]2d^5 - c^3d^2 +8cd^4 +1,[/tex]
x = [tex]8d^5 - 3c^3d2 +5c^2d^3 - 4cd^4 +9\\[/tex] - ( [tex]2d^5 - c^3d^2 +8cd^4 +1,[/tex])
x = [tex]6d^5 - 2c^3d^2+ 5c^2d^3 - 12cd^4 +8[/tex]

Step-by-step explanation:
2x + 4y = 36
2 × 4 + 4y = 36
8 + 4y = 36
4y = 36 - 8

Answer:
x = 3 oz of seeds
y = 7 oz of seeds
Step-by-step explanation:
1. x + y = 10 oz (total amount of snack mix in ounces; oz)
2. $1.50x + $2.50y = $22 (how much the seeds and dried fruit costs)
3. Solve the system of equations using algebra.
$1.50 x + $1.50y = $15
$1.50 x + $2.50y = $22
There are $1.50x's in both of the equations, so cancel them out.
Subtract $2.50y by $1.50y and $22 by $15. y = 7
4. Plug in the y value in one of the equations.
x + 7 = 10; x = 3
Solve for x. Round to the nearest tenth, if necessary.
x = 1.3 (to the nearest tenth)

The length of a box is twice the width and thrice the height. If the volume of the box is 288 m then find the dimensions of the box
Answer:
length = 12 mwidth = 6 mheight = 4 mStep-by-step explanation:
Let the height be x.
Length is 3 thrice the height, so length ⇒ 3xLength is twice the width, so width ⇒ 3x/2We know the formula for volume of the box.
V = lwhV = (3x)(3x/2)(x)288 = 9x³/29x³ = 576x³ = 64x = 4 mDimensions
height = x = 4 mwidth = 3x/2 = 3(4)/2 = 6 mlength = 3x = 3(4) = 12 m
