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
Answer:
130
Step-by-step explanation:
X is the alternate corresponding angle to 50. 50+y=180
y=130
x and y = the same thing so 130 is the value of x
Answer:
A 500 mg bag of prepackage seeds costing $3.95
Step-by-step explanation:
First, you need to know the amoun of grams in 1/2 kg to find the cost of the sunflower seeds:
1 kg→1000 grams
1/2 kg→ x
x=(1000*(1/2))/1
x= 1000/2
x= 500 grams
Second, you have to find the cost of 500 grams of sunflower seeds:
100 grams → $0.70
500 grams→ x
x=(500 *0.70)/100
x= 3.5
According to this, 1/2 kg of of bulk sunflower seeds cost $3.5 which is cheaper than the 500 mg bag of prepackage seeds that cost $3.95 and this means that the better value is 1/2 kg of bulk sunflower seeds as the amount is also higher as 500 mg is equal to 0.5 grams.
