How much is it to buy 10 meters of fleece when the rate is $1.60/ft of fabric
1 answer:
You will have to convert meters to feet because the price is connected to feet.
1 foot is approximately equal to .3048 m.
First, you can set up a ratio problem to find out how many feet are in 10 meters.
x 10 m = 32.81 ft (when rounded to 2nd decimal place)
Then, you can multiply this by $1.60 to find out how much your fabric would cost total.
$1.60 / 1 ft x 32.81 ft = $49.30 (when rounded to 2nd decimal place as you have to do with money)

Answer: 4(2x²+9) or
Step-by-step explanation:
To solve the equation by factoring, we want to set the equation to zero. In order to have the equation equal to zero, we want to add both sides by 36.
8x²=-36 [add both sides by 36]
8x²+36=0
When it comes to factoring, we want to pull out numbers or variables that are common in each term.
8x²+36=0 [take out a 4 in each term]
4(2x²+9)=0
It may seem that 2x²+9 can be factored further, it actually can't. This tells us that the factored form of the equation is 4(2x²+9)=0.
To solve the equation, we want to find the value of x. We already know the graph does not cross the x-axis because the y-intercept or vertex is (0,9).
4(2x²+9)=0 [divide both sides by 4]
2x²+9=0 [subtract both sides by 9]
2x²=-9 [divide both sides by 2]
x²=-9/2 [square root both sides]
