4x^2-7x=15<br> Solve by factoring and please please please explain or show the work

vodomira [7]

Answer:

x=3 and x=-1.25

Step-by-step explanation:

4x^2-7x=15

subtract 15 from each side:

4x^2-7x-15=0

factor (trying different numbers that the sum is 7 and the quotient is 15)

(2x-6 )(2x+2.5 )=0

2x-6=0 add 6 to each side

2x=6

x=3

2x+2.5=0 subtract 2.5 from each side

2x=-2.5

x=-1.25

Write each percent as a fraction and as a mixed number or fraction 325% 480% 0.6%

ExtremeBDS [4]

325%=3.25 which is $\frac{325}{100}$ or $3\frac{25}{100}$ which can be reduced to $3\frac{1}{4}$

480%=4.80 which is $\frac{480}{100}$ or $4\frac{80}{100}$ which can be reduced to $4\frac{4}{5}$

0.6%=0.006 which is $\frac{3}{500}$

I hope this helps.
