Answer:11(x−2)(x+4)
Step-by-step explanation:
11x2+22x−88
=11(x−2)(x+4)
-3x + 2y + z = -6
(3)x + 3y + 2z = 5(3) We want to get rid of any variable within 2 equations. The easiest one would be by multiplying both sides of eq#2 by 3 and add it to eq#1.
-3x+2y+z=-6
3x+9y+6z=15
Add them together to get 11y+7z=9
(-4)x+3y+2z=5(-4) Now,multiply the original eq#2 by -4 to cancel out x in the last equation
-4x-12y-8z=-20
4x + 4y + 3z = 13
add them together to get -8y-5z=-7
Now multiply the eq 11y+7z=9 by 5 and the equation -8y-5z=-7 by 7 to cancel out the z variable when we add them together.
Once we multiply them, we get
-56y-35z=-49
55y+35z=45
add them together to get -y=-4 and we know y=4
substitute y into any equation here that has y and any other 1 variable like -8y-5z=-7 and get z=-5
Finally, we know y=4 and z=-5, we can substitue that into any of the original eqs like -3x + 2y + z = -6 and we get x=-3
To check, just substitute these values into any of the equations above
Step-by-step explanation:
A. Dad = 50, Mum = 47, Sister = 22
me = 19
Total Sum = 50 + 47 + 22 + 19
= 136
√136 = 11.662.
B. + 1435 797 202 = 40
√40 = 6.33
C. BRYAN = 2 + 18 + 25 + 14 = 59
√59 = 7.68.
