The answer would be 132 because the formula for find circumference while using radius is 2(3.14)r .
C= 2(3.13)21
C= 6.28 • 21 = 131.88
131.88 rounded is 132
Answer: $8,020
Steps:
$8,600 * 2yrs = $17,200
$1,600 * 2yrs = $3200
$3200 + $5980 = $9180
$17,200 - $9,180 = $8,020
She need to save $8, 020 more
I would appreciate brainliest if This was helpful and correct! :)
4 x^2 + 20 x + 25 = 7
Divide both sides by 4:
x^2 + 5 x + 25/4 = 7/4
Write the left-hand side as a square:
(x + 5/2)^2 = 7/4
Take the square root of both sides:
x + 5/2 = sqrt(7)/2 or x + 5/2 = -sqrt(7)/2
Subtract 5/2 from both sides:
x = sqrt(7)/2 - 5/2 or x + 5/2 = -sqrt(7)/2
Subtract 5/2 from both sides:
Answer: x = sqrt(7)/2 - 5/2 or x = -5/2 - sqrt(7)/2
Answer:
1
Step-by-step explanation:
Because there are no squares
We just need to know the sin 40 value
