1) both 8x and -6x are the same form - they’re just a coefficient with a variable, while 9 and -7 are just plain numbers. move the expression around as shown in the picture: 8x - 6x + 9 - 7. now coefficients with variables are next to each other, while plain numbers are next to each other, making it easier to solve.
2) now solve: 8x - 6x is 2x, and 9 - 7 is 2. now you have 2x + 2, which is the final answer.

i don’t know if i explained it very well, but if you look at the picture you should be fine.

Answer:

1.the square pan is larger by 12 inches

40 cm^2

Step-by-step explanation:

The difference in size can be determined by calculating the difference between the perimeter of the square pan and the circumference of a circle

perimeter of a square = 4 x length

14 x 4 = 56 inches

Circumference of a circle = πD = (22/7) x 14 = 44 inches

Difference in size = 56 - 44 = 12 inches

Area of a rectangle = length x width

10 x 4 - 40 cm^2

<span> The distributive property is a special way where multiplication is applied to addition of two or more numbers in which each term inside a set of parentheses can be multiplied by a factor outside the parentheses, such as:
</span>

<span>a(b + c) = ab + ac.

Does this help in any way?
