Answer:
36
Step-by-step explanation:
4 was multiplied 6 times to get 24. Therefore you must multiply 7 by 6 as well.
Answer: Distributive property of the multiplication.
Step-by-step explanation:
You did not post Gretchen's expression, but i gues that it is 3*(x + y)
I guess that it is the distributive property of the multiplication.
For 3 numbers, A, B and C, we have that:
A*(B + C) = A*B + A*C
here we have:
3*x + 3*y
We can do the inverse process to the distributive property, and get:
3*x + 3*y = 3*(x + y)
which i guess is Gretchen's expression.
Answer:
3x-y=6?
Step-by-step explanation:
Answer:
Step-by-step explanation:
average of x-coordinates of A and B = (4-8)/2 = -2
average of y-coordinates of A and B = (-4+2)/2 = -1
midpoint of AB: M(-2,-1)
Answer:
X=2
Step-by-step explanation:
You can prove the triangle congruent by SAS. First, reflexive property and then isosceles triangle theorem since two side is congruent, the opposite angle is congruent to each other because of that theorem and then cpctc
