h + 6h = 7h
2 goes into 102 51 times. (102 divided by 2 equals 51)
V = pi r^2*H & V = pi (4r)^2*h Equate pi r^(2)H= pi (4r)^2 h pi cancel down r^(2)H = (4r)^2h r^(2)*H = 16r^(2)*h 'r^(2) cancels down H= 16h h = H/16 This means is you increase the radius by '4 times' , then you reduce the height(H) by '16 times' in order to maintain the same volume.
Let the numbers be 'm' & 'n' Hence mn = 51 (Multiplication) m + n = -16 (Addition) Algebraically rearrange m = -16 -n Ssubstitute (-16-n) n = 51 -16n - n^2 = 51 n^(2) + 16n + 51 = 0 ( It is now in Quadratic form to solve). Complete the Square (n + 8)^2 - 8^(2) = -51 (n + 8)^2 = -51 + 64 = 13 Square root both sides n + 8 = +/-sqrt(13) n + 8 = +/- 3.60555.... n = -13.60555.... & -4.39444.... Are the two number.
multiplication is point to point and convolustion is point to multi-point ex multiplication-- s[n]=x[n].h[n] s[0]=[x[0].h[0] s[1]=[x[1].h[1] s[2]=[x[2].h[2] . . . .. s[n-1]=[x[n-1].h[n-1] convollustion s[n]=x[n]*h[n] s[0]=[x[0].h[0]+x[0].h[1]+x[0].h[2]+.......+x[0].h[n-1] s[1]=[x[1].h[0]+x[1].h[1]+x[1].h[2]+.......+x[1].h[n-1] s[2]=[x[2].h[2]+x[2].h[1]+x[2].h[2]+.......+x[2].h[n-1] . . . s[n-1]=[x[n-1].h[0]+x[n-1].h[1]+x[n-1].h[2]+.......+x[n-1].h[n-1].
7h - 2 - 51 is an expression NOT an equation. An expression cannot be solved for the value of a variable.
(7h + 35) / (-7) = (7h)/(-7) + (35)/(-7) = (-h) + (-5) = - (h + 5)
h + 6h = 7h
Unless you have a value for 'h', the answer will just be an expression: 10 + 7h
1-h
If: 7h+4 = -80 then h = -12
h = 0.538462 14 + 5h + 2h = 5h + 28h 14 + 7h = 33h 14 + 7h - 7h = 33h - 7h 14 = 26h 14/26 = 26/26h 0..538462 = h
The value of h is 9
7h+39=60 Take away 39 from both sides (called isolating your variable) 7h=21 Divide by seven, because (I assume) you are looking for h, not 7h h=3 And to check: 7(3)+39=60 21+39=60 60=60
a=bh/2 51=3(h)/2 17=h/2 h=34m
I would not fully go by my answer but I think its h=6
-7h = 35h = -5
