Thanks you bro
Continue from where he stop. You get -4x and -5x for the factor. Complete it.
The answer is= -13/(3x-2)^2. But the answer they are post is incorrect answer.
Okay; let,(x-y)^2=x^2+y^2-2xy. But,x-y=7 and x^2+y^2=25.by apply the formula. (7)^2=25-2xy 49=25-2xy xy=-12. Then also, (x+y)^2=(x-y)^2+4xy (x+y)^2=49-48. X+y=+/-1. Then solve the eqn. X+y=+/-1 x-y=7. Then x=3 or 4. Y=-3 or -4.
Let sm=a*3=3a lg=b*2=2b 2b-3a=-1-----eqn 1 b+2a=24----eqn2, then a=7 b=10.
Let the no be x,y,z x+y+z=14 z=4x x+2z=18 from eqn 3 x+2(4x)=18 x+8x=18 9x=18 x=2,sub into eqn 2 z=4(2) z=8 y=4.
Answer=c,bcos there is no solution occur.
By simplify: we get (27)^1/3 * (x^4)^1/3 * (y^6)^1/3 =3y^2x^4/3
Just input x as the base to both sides,then convert it to base 10 and u will get value for x. At final,we get; x=2.
By using completing the square method amd also apply all the rule involve to it. hence, you will get t=-u+/- sqrtu^2+2as/a
Let u=0 and a=g=9.8m/s^2 and t=0.5s. Use: d=ut+1/2at^2 d=1/2at^2 d=4.9*(0.5)^2 d=1.2m in 1.d.p
I support steve,he is correct.
2. X^2+y^2=33/4 3.(x-y)(x+y)(x-y).
Answer1=5x+5y+5z and Ans2=w(x+y).
The answer is =6360
By introduce log and divide the coefficient of x,then got ur answer in 2.d.p
By firstly change the decimal to fractio. So, 200000*(105/100)^3. Answer=2.31525*10^11/1000000=231,525.
U can still use this method too: step by step: 2^x=4x,then divide both side by 4,you get; 2^x/4=x,then 2^x-2=x. Then look for antilog of x by using try and error. Hence, we find x=4. Then 2^4-2=4,by prove l.h.s=r.h.s. Then, 2^2=4. 4=4. There4,x=4. Hope
Let say,3^x=m and x=cuberoot3. We get m=9cuberoot3,then take cube to both side; we get m^3=729m,divid both side by m; we get m^2=729.then,m=27 but 3^x=m and m=27; so,3^x=3^3. There4, x=3.
Step by step explanation: let find ratio; r=d2/d1=d3/d2.then equal to, 2x+2/x =3x+3/2x+2,then cross multiply. (2x+2)^2=x(3x+3). 4x^2+8x+4=3x^2+3x. There4, x^2+5x+4=0 by solve the equation,we get x=-1or-4. So,when x=-1,the series is -1,0,0. So,t4=0. But
Caden u ar wrong
C=k-273. Am i correct
Pls can u help me to solve: x+y+z=1,x^2+y^2+z^2=34 and x^3+y^3+z^3=94
Yes,thanks
By using b^2=4ac: x^2 =16^2. 1=4*1*16^x. 1=2^2+4x. So let x=-1/2. 1=1.
