7m2 + 6.5n - 4n + 2.5m2 - n = 9.5m2 + 1.5n
4n -14 = 22 4n = 22+14 4n = 36 n = 9
4n -32 = -28
n=10/7. i did this one mentally. but are you sure its 8n minus negative 4n or is it 8n minus 4n? 8n- -4n does not equal 8n-4n 8n- -4n is the same as 8n+4n
the value of 4n + 2 = 14
4n is multiplied by 4n.
7m2 + 6.5n - 4n + 2.5m2 - n = 9.5m2 + 1.5n
Yes, they are. Sketch of proof: Odd square root is a number x of form x = 2n + 1. Square of this root is: x2=(2n+1)2=4n2+4n+1=y, which can be expressed as: y=2(2n2+2n)+1. Let t = 2n2+2n. Then, y=2t+1, which is an odd number.
It is 4n/63
square of (n x 2)
4n -14 = 22 4n = 22+14 4n = 36 n = 9
4 + 4n - 12 = 4n - 8
4n + 3 = 15 4n +3 - 3 = 15 - 3 4n = 12 4n/4 = 12/4 n = 3
-n + 4n = 4n - n = 3n Done!!!!!
That factors to 3(m - 4n)(6m - n)
4n-32 = -28
28-4n = 24
