For Addition, if the signs are the same, you add and keep the sign. And if they are different, you subtract and keep the sign of the greater absolute value.
For Subtraction, You change the subtraction sign to the addition one and then follow the rules of addition, above.

Which of the following are solutions to the equation below?

Reptile [31]

Answer:

Option B and D

Step-by-step explanation:

Subtract 9 from both sides :

4x² + 4x - 8 = 0

Divide both sides by 4 :

x² + x - 2 = 0

Factorise using factorisation method :

x² - x + 2x -2 = 0

x(x - 1) +2(x-1) = 0

(x+2)(x-1) = 0

Solve for x

x +2 = 0 OR x - 1 = 0

x = -2 OR x = 1

Answer will be Option B and D

Hope this helped and have a good day

Answer:

Step-by-step explanation:

For Mr Rowley,

Ratio of Number of home works to the number of exit tickets = $\frac{12}{14}$

= $\frac{6}{7}$

= 6:7

For Ms Rivera,

Ratio of Number of home works to the number of exit tickets = $\frac{36}{42}$

= $\frac{6}{7}$

= 6:7

Since, both the ratios are same, fractions will be proportional.

$\frac{12}{14}=\frac{36}{42}$
