3*1=34 --> split this into two parts. 3*1 is 3 and 3+1 is 4 so put them together and you get 34.
<span>x^2 - 12x - 45
= (x - 15) (x + 3) .........</span><span>factored form</span>
A = a^2.....where " a " is the length of one side
A = 79
79 = a^2...take sqrt of both sides, eliminating the ^2
sqrt 79 = a
8.89 = a
so the length of one side is approximately 8.89 ft <==
Answer:
4% Hope this helped.
Step-by-step explanation:
The formula is: final value minus starting value divided by the starting value then times 100
THIS FORMULA ONLY APPLIES TO PERCENT INCREASE
<u>Final Value−Starting Value</u>
Starting Value x100
Plug numbers in
2600-2500/2500 x 100
100/2500=0.04
0.04x100
=4%
