Answer: 3. Distributive
Step-by-step explanation:
Distributive property of multiplication over addition is the only property that is require to multiply an expression to the other expression with two or more than two terms.
For example: a (b+c)= a b+ac , where a,b,c can be any expression.
Given expression: -5(x-3) = -5x +15 , which illustrates the distributive property of multiplication over addition.
Hence, the correct option is 3. Distributive.
The rest of properties cannot work for multiplication over addition as they are used for one operation.

Answer:
f(3) = 7
Step-by-step explanation:
f (x)=x + 4
Let x=3
f (3)=3 + 4
f(3) = 7
You must apply the following formula to calculate the area a triangle:
A=bxh/2
b=12 inches (the base of the triangle)
h=12.5 inches (the height of the triangle)
When you substitute these values into the formula, you obtain:
A=bxh/2
A=(12 inches)(12.5 inches)/2
A=75 inches²

You already have the area of one triangle. So, you only have to multiply this area by 7, because the seven (7) triangles are congruent, which means that they have the same area:

At=Ax7
At=(75 inches²)(7)
At=525 inches²
