Answer:
The distributive property means that to multiply 3(x-4), you distribute the 3 by multiplying both x and -4 by 3. Therefore, the answer here is (3*x)+(3*-4), which is equal to 3x-12.
Hope this helps!

There are 13 white marbles in the bag.
Step-by-step explanation:
Given,
Total number of marbles = 24
Let,
x represent the number of white marbles.
y represent the number of yellow marbles.
According to given statement;
x+y=24 Eqn 1
x = 2y-9 Eqn 2
Putting value of x from Eqn 2 in Eqn 1

Dividing both sides by 3

Putting y=11 in Eqn 2

There are 13 white marbles in the bag.

Answer:
7.5
Step-by-step explanation:
If we look at the 4 by 4 square around the triangle we can just do the area of the square minus the area of the 3 little triangles which is:
4 * 4 - 4 * 1 / 2 - 3 * 3 / 2 - 4 * 1 / 2
= 16 - 2 - 4.5 - 2
= 16 - 8.5
= 7.5
