Multiply 100 times 5 in your head to get 500,
100 * 5 = 500
90 * 5 = 450
8 * 5 = 40
Put those 3 together into one equation, \/
(100 * 5) + (90 * 5) + (8 * 5) = 990 OR (100 * 5) + (98 * 5) = 990
depends on how distributed the teacher wants it to be.
It is (d+5)(d+5) because 5•5 is 25 and 5+5 is 10
Since you answered the first 2 i can go to c and d.
C can really be anything since it's being multiplied by 0 no matter what you put there it will be 0.
But for D it's 1/10^2
Hope this helps ^^
Yes in order for them to be symmetrical they both have to be Symmetrical or the same
3^2 + 4^2 = c^2
sqrt(9) + sqrt(16) = c^2
Sqrt(25) = c^2
C = 5
