20% of 16 which is. 10%=1.6 and another that would = 3.12
Add 2 3/4 and 2 1/2 and you’ll get ur answer. area means total and when u see area, it means add
Answer:
Step-by-step explanation:
cosx=(adjacent side)/(hypotenuse)
cosB=3/5
Solve for x:
x^2 + 4 x + 25 = 0 I ssume that's the notation.
Subtract 25 from both sides:
x^2 + 4 x = -25
Add 4 to both sides:
x^2 + 4 x + 4 = -21
Write the left hand side as a square:
(x + 2)^2 = -21
Take the square root of both sides:
x + 2 = i sqrt(21) or x + 2 = -i sqrt(21)
Subtract 2 from both sides:
x = i sqrt(21) - 2 or x + 2 = -i sqrt(21)
Subtract 2 from both sides:
Answer: x = i sqrt(21) - 2 or x = -i sqrt(21) - 2
Number 52 does not belong because 52 is a prime number
