Answer:
x=2
Step-by-step explanation:
Distribute the second bracket:
![2x-7-x+5=0](https://tex.z-dn.net/?f=%202x-7-x%2B5%3D0)
Sum similar terms, bringing all number right of the equal sign - careful, they change sign!
![2x-x = 7-5\\x=2](https://tex.z-dn.net/?f=%202x-x%20%3D%207-5%5C%5C%3C%2Fp%3E%3Cp%3Ex%3D2%20)
Answer:
x=5 x=3
Step-by-step explanation:
f(x) = x^2 - 8x+ 15
Factor
What two numbers multiply to 15 and add to -8
-5*-3 = 15
-5+-3 = -8
f(x) = (x-5) (x-3)
Setting equal to 0
0= (x-5) (x-3)
Using the zero product property
x-5 =0 x-3=0
x=5 x=3

Answer:
15/40
Step-by-step explanation:
The difference between denominator and numerator in 3/8 is 8-3 = 5. In order to get an equal-value fraction with that difference being 25, each of the numbers must be multiplied by 5:
3/8 = 15/40
The number is 15/40.
