Step-by-step explanation:
No explaintion sorry.
Hope this helps!
You can rewrite radical form expressions by putting the expression to the power of 1/n, n depending on the radical. For example: sqrt2 = 2^(1/2) or cuberoot4= 4^(1/3). Vice versa with rational exponent equations: 5^(1/2) = sqrt5 or 3^4/3 = cuberoot3^4
Option B;
A suitable x-coefficient for a quadratic function that factors into a perfect square has to be even.
Answer:
b = 10/3
Step-by-step explanation:
39=1 3/10b would be clearer if rewritten as 39 = (1 3/10)b. We are to solve this for the value of b.
Rewrite the mixed number 1 3/10 as 13/10. Then we have 39 = (13/10)b.
To isolate b, multiply both sides of this equation by 10/13:
10
---- * 39 = b, or b = 10/3
13
