Answer:

infinite solutions

Step-by-step explanation:

5d + 2(2-d) = 3(1+d) + 1

Distribute

5d + 4-2d = 3 +3d +1

Combine like terms

3d +4 = 3d+4

Subtract 3d from each side

3d-3d +4 = 3d-3d +4

4=4

Since this is always true

d has infinite solutions

Which of the following represents the sum of the polynomials below?

zysi [14]

Answer:

Step-by-step explanation:

First, you have to align the like terms next to each other so that it will be easier to combine like terms. (Like terms have the same variables and powers)

$6x^3+(-2x^3)+2x^2+5x^2+9x+3x$

Combine like terms:

(When combining like terms all you have to do is add/subtract the coefficients, number in front of variables, and leave the variable and exponents)

$6x^3+(-2x^3)= > 6x^3-2x^3=4x^3$

$2x^2+5x^2=7x^2$

$9x+3x=12x$

So, we get $4x^3+7x^2+12x$

What is the value of y? Enter your answer in the box.

Scrat [10]

Answer:

y = 20

Step-by-step explanation:

Since AB and AC are congruent then the triangle is isosceles, thus

∠B = ∠C = 25°

To find ∠A subtract the sum of the 2 angles from 180°

∠A = 180° - (25 + 25)° = 180° - 50° = 130°, thus

3y + 70 = 130 ( subtract 70 from both sides )

3y = 60 ( divide both sides by 3 )

y = 20
