Answer:
(58-11) divided by 20
Step-by-step explanation:
Answer:
x = 5 or x = 1
Step-by-step explanation:
x² - 6x + 7 = 0
x² - 6x = -7
x² - 6x + 9 = -7 + 9 1/2 of the x term than square it and add it the both sides.
(x - 3)(x - 3) = 2
( x -3)² = 2
= 
(x - 3) = ± 2
x - 3 = 2 or x - 3 = -2
x = 5 or x = 1
Answer:
rearrange them properly to get
x-y=7
-3x+y=12
( by elimination method)
x-y = 7
-3x+y=
(x+ –3x) + (–y+y) = (7+12)
-2x+0= 19
x= -9.5
from eqn(i)
x-y=7
-9.5 - y=7
-y=16.5
y= -16.5
Answer:
x = 6•3 == 18
18² = 324
324 + 2 + 11 = 337
<h2>337</h2>
