X=−1+√17 or x=−1−√17 is the answer.
Jobisdone [24]3 years ago
5 0
First get the equation to equal 0 by subtracting 17 from both sides.
You should have x^2+2x-16=0
Next plug your numbers into the quadratic formula(-b^2+/- the square root of b^2-4ac -all divided by 2a)
The end result should be x=-1+/- the square root of 17 or(if you want the decimal) 3.12310562, -5.12310562

How to put percent into decimal
fiasKO [112]

Answer:

There are multiple ways to do so:

You can divide the number by 100 to convert it to a decimal

You could take your percentage and add a decimal two places to the left.

Examples of both:

For division its as simple as 75 divided by 100 = 0.75

If we are going to use the decimal method, lets say we have 45%, so we can do this:

45% =45.00

Move the decimal two places to the left.

0.45

Alyssa wants to buy a new car and is planning to take out a loan to pay for the car.
g100num [7]

Answer: the amount of interest that Alyssa will pay on her loan is $1320

Step-by-step explanation:

The formula for determining simple interest is expressed as

I = PRT/100

Where

I represents interest paid on the loan.

P represents the principal or amount taken as loan

R represents interest rate

T represents the duration of the loan in years.

From the information given,

P = $22000

R = 4.5%

T = 4 years

Therefore,

I = (22000 × 1.5 × 4)/ 100

I = 132000/100 = $1320

Solve the equation: w^2+7w+12=0
polet [3.4K]
Hi there!
We are given the equation w² + 7w + 12 = 0, and we are told to solve it. Well, we can first take all the factors of 12 -
1 12
2 6
3  4
Now, take the sum of each factor pair -
1, 12 = 13
2, 6 = 8
3, 4 = 7
Find which factor pair adds up to 7, and we can see that 3 and 4 add up to seven, while also having a product of 12. Therefore, since the whole equation has addition signs, we can factor the equation w² + 7w + 12 into (w + 3)(w + 4) = 0. Next, using the Zero Product Property, we can set each term to zero.
w + 3 = 0
w = -3

w + 4 = 0
w = -4
Therefore, the solution to the equation w² + 7w + 12 = 0 is w = -3, -4. Hope this helped and have a great day!
