a. 7x + 52 (2x + 5x) (40 + 12)
b. 13x + 142 (2x+5x+6x) (40 + 12 - 10)
c. 246 (16 + 40 + 40 + 100 + 12 + 48 - 10)
Answer:
x=2 and y=1
Step-by-step explanation:
if y is 1 then u can multiply the three and 4 which is the same and then add 2 which add up to 5 and 6
Use this formula: C=2πr. Divide 14/2 to get the radius. Substitute the radius into the formula.
The answer is 14pi units.

Answer:
Distance =√(x₁ - y₁)²+ (x₂ - y₂)² = √97 = 9.85
Step-by-step explanation:
The Matrix X and Y could also be referred to as vectors in Rⁿ dimensions.
if Vector X = ( x₁ , x₂) and Vector Y = (y₁ , y₂)
then, Distance (X-Y) = ||X-Y|| = √(x₁ - y₁)²+ (x₂ - y₂)²
where, x₁ = 8, x₂ = -5 and y₁ = -1 , y₂ = -9
Distance = √(8 - (-1))²+ (-5 - (-9))² = √9² + 4² =√97 = 9.85
