ANSWER
By simplifying the left hand side using the Pythagorean Identity.
EXPLANATION
The given identity is
Take the left hand side and simplify to get the right hand side.
Collect LCM for the denominators.
Recall the Pythagorean Identity.
This implies that:
We substitute this to get,
A = 2w+5
example: on week three, she would have the recipes from the other weeks that you have to account for as well as the extra five
2(3)+5=11 so A would equal 11 by week three.
Use multiplication because it is essentially repeated addition.
2(from week 1) + 2(from week 2) + 2(from week 3) + 5(prior to school) =11
All you have to do is combine like terms. 2c and (-c) are like terms (-5b) and (-b) are like terms and a is a term. So, 2c combined with (-c) is C. (-5b) and (-b) combined is (-6b). Since a doesnt need to be combined with anything, you leave it as it is so your answer will then be c - 6b + a (this is the answer assuming that there is a + in front of the a. If there is a - sign, then just change your +a to -a at the end
If one foot is equivalent to 0.3048 meters, then <span>0.3048 x 65 feet should give us our answer.
</span>0.3048 x 65 feet = 19.812.
19.812 rounded to the nearest tenth is 19.8.
