Break it down it’s a lot easier
So first I split 30xy into two numbers that were divisible by both 9 and 25, and that's how I got 15xy+15xy, after that it's just simple factorisation
Answer:
180 - 84 = z
Step-by-step explanation:
all angles in a triangle should add up to 180. If both angles add up to 84 (42 + 42) all theres left to do is to substract 84 from 180 to find z :)
2: 4 is a factor and multiple of 8. 8 and 4 is also even numbers so is is most likely to be divisible by any number
A unit circle has its center at the origin and has a radius of one. It is modeled by the equation
x² + y² = 1
We are given with <span>(x,-1)</span> .
Solving for x
x² + (-1)² = 1
x = 0<span />
