You multiply top and bottom of the fraction by the conjugate of 5 - √2 which is 5 + √2. This produces a rational denominator:-
= √7 ( 5 + √2) / (5 - √2)(5 + √2)
= √7 ( 5 + √2) / (25 -2)
= (√7 ( 5 + √2)) / 23 answer
1. You divide by 100 to find the decimal version of any percentage, and do the opposite for vise versa
Answer:
Step-by-step explanation:
By definition you have that:
Based on the figure attached in the problem you have that:
Therefore, you must substitute the above into
Then, the answer is:
Answer:
6 (v-3)^2
Step-by-step explanation:
6v^2–36v+54
Factor out a 6
6(v^2–6v+9)
Then factor inside the parentheses
What 2 numbers multiply to 9 and add to -6
-3*-3 =9 -3+-3 = -6
6( v-3)(v-3)
6 (v-3)^2
