I don't get adding integers with different signs!!
5+(-2)=?

Answers

Answer 1

Answer: think of it as subtracting your adding a negative number to a positive, if the positive number is larger when adding, then your answer should end up positive if the negative number is larger your answer should be negative, in this case you could think of this problem as 5-2 instead of adding the 5 to the negative 2. so in this case your answer would be 3. if you don't get it try using a number line, those are very helpful when starting off!

Answer 2

Answer: Well,

5 + (-2)

"Five plus the quantity negative two."

Adding a negative quantity is the same as subtracting the positive quantity.

For example: 0 + (-1) = 0 - 1 = -1

Another situation: 0 - (+1)

You have to realize that any number (say 5, for example) without a sign in front of it is automatically positive.

Technically, if we "show signs," we will get +0 - (+1)

We can really just omit ("hide signs") the positive signs.
0 - 1 = -1

Yet another situation: 0 - (-1)

Subtracting a negative can be re-worded as "subtracting from the negative." It sounds like it is taking away from the negative, bringing the integer closer to zero. Subtracting a negative is the same as adding a positive.
0 - (-1) = 0 + (+1) or 0 + 1 = 1

In your case: 5 + (-2):
5 + (-2) = 5 - 2 or 3 or +3

Area of Rectangle = 8 × 7
= 56cm^2

Length of side of Square = 7-4
= 3cm

Area of Square = 3 × 3
= 9 cm^2
Length of triangle = 8 - 3
= 5cm
Area of triangle = 1/2 × 5 × 3
= 7.5 cm^2

Hope this helps :)

So you multiply 8 and four to give you 32 which is the area of the rectangle, subtract the top measurement of 7 by 4 to give you 3 which will make it simpler to find the area of the square and triangle. To find the area of the square multiply 3 by 3 to get 9. And to find the triangle since we know that 8 minus 3 is 5 and to find the area of a triangle we have to divide by two at the end 5x3 divided by 2 will give you the answer of 7.5. To find the total area do 32+9+7.5
to get 48.5cm squared
