Answer:

Option B: x = 15 is a solution, but x = 9 is not is the correct answer.

Step-by-step explanation:

Given equation is:

x - 3 = 12

The solutions we have to check are;

x = 9 and x = 15

Putting x = 9 in the given equation;

9 - 3 = 12

6 ≠ 12

Putting x = 15 in the given equation;

15 - 3 = 12

12 = 12

Hence,

Option B: x = 15 is a solution, but x = 9 is not is the correct answer.

Answer:

x = 54

Step-by-step explanation:

These angles are complementary because they add up to 90:

x - 7 + 43 = 90

x + 36 = 90

x = 90 - 36

x = 54

Find: (4x2y3 + 2xy2 – 2y) – (–7x2y3 + 6xy2 – 2y) Place the correct coefficients in the difference.

Answer: Our required answer will be

$11x^2y^3-4xy^2$

Step-by-step explanation:

Since we have given that

$(4x^y^3+2xy^2-2y)-(-7x^2y^3+6xy^2-2y)$

We need to get the difference:

1) We first open the second bracket and make appropriate change in signs :

$4x^y^3+2xy^2-2y+7x^2y^3-6xy^2+2y$

2) Gather the like terms together :

$4x^2y^3+2xy^2-2y+7x^2y^3-6xy^2+2y\\\\=4x^2y^3+7x^2y^3+2xy^2-6xy^2-2y+2y\\\\=11x^2y^3-4xy^2$

Hence, our required answer will be

$11x^2y^3-4xy^2$
