Answer: x=25, y=19
Step-by-step explanation: Because the triangle is equilateral, all the angles must be equal to 60 degrees. So 2x+10=60. 2x=50 and x=25. Then the same thing: 3y+3=60. 3y=57, y=19.
N-1(-1/2) is the formula because the sequence is taking half of the previous number and changing its sign
4(x+8)
because 4 is the greatest common factor of 4 and 32. you distribute the 4 into the parenthesis and get 4x+32
so let's take a circle with radius (r) = 3cm
Area of the circle = πr² = 3.14 × 3² = 3.14 × 9 = 28.26cm²
