Answer: A
Step-by-step explanation:
Sally: 66/3=22
Molly: 72/4=18
22-18=4
Answer:
I'm pretty sure the answer is -a²b and 5a²b
Step-by-step explanation:
Yes, it is. You may prove it using something like this: 1 is an integer. 1-1 is a difference between integers. A difference between integers returns an integer, so 0 is an integer.
X=70, y=55
The triangle is an isosceles triangles. In an isosceles triangle, the base angles are congruent.
Then use the triangle angle sum theorem and set the equation to 180.
55+55+x=180
110+x=180
x=70
The angle with 55 degrees and the angle with the variable y are alternate angles. Meaning they are congruent.
