Answer:

See explanation:

Step-by-step explanation:

Let a and b be integers.

Sum means addition.

So we are trying to figure out what a+b equals.

It could result in as 0, negative, or positive.

a+b is 0 when a and b are of opposite values. Example: 5+(-5) or -5+5 is 0 because 5 and -5 are opposite values.

a+b is positive when both a and b are positive. Example 5+3=5.

a+b is positive when |a|>|b| and a is positive. Example:  5+(-3)=2 since |5|>|-3| and 5 is positive.

a+b is positive when |a|<|b| and b is positive. Example:  -3+5=2 since |-3|<|5| and 5 is positive.

a+b is negative when both a and b are negative. Example: -5+(-3)=-8.

a+b is negative when |a|>|b| and a is negative. Example: -5+3=-2 since |-5|>|3| and -5 is negative.

a+b is negative when |a|<|b| and b is negative. Example: 3+(-5)=-2 since      |3|<|-5| and -5 is negative.

How many solutions will this system of equations have? (2 points)
Agata [3.3K]
The answer is infinitely many solutions

If you divide the 2nd equation by 3, you get the first equation, meaning they are identical. That means that any value of x will be true, which means there are infinite solutions

Answer:

B. 3 square feet

Step-by-step explanation:

The formula for surface area is:

2lw+2lh+2wh

Box F's surface area is just plugging in those variables

2(3)(3)+2(3)(3)+2(3)(3)=54

Box J's surface area is the same way

2(2)(4.5)+2(2)(3)+2(4.5)(3)=57

The difference is 57-54=3

The answer is B. 3 square ft
