Answer:
25.9%
Step-by-step explanation:
100000÷13500×100
Subtract the 74.074 because 100000 is 74.074 of 135000
Factor out the 4 in both equations
8a^2-20^2=(2^2 times a^2 times 2)-(2^2 times 5)
therefor it is also equal to
(2a)^2 times 2-(2^2 times 5)
we can force it into a difference of 2 perfect squares which is a^2-b^2=(a-b)(a+b)
(2a√2)^2-(2√5)^2=((2a√2)-(2√5))((2a√2)+(2√5))
Distributive property because if you divide -5.2+(-8.4) by -1, you get -(5.2+8.4)
6+9=15
y+9=x
x=30
y+9=30
y=21
