Answer:
Step-by-step explanation:
2x - y + z = 4
4x - 2y + 2z = 8
-x + 3y - z = 5
2x - y + z = 4
-x + 3y - z = 5
x + 2y = 9
4x - 2y + 2z = 8
-2x + 6y - 2z = 10
2x + 4y = 18
x + 2y = 9
2x + 4y = 18
-2x - 4y = -18
2x + 4y = 18
0 =0

Step-by-step explanation:
Answer: option D
Step-by-step explanation:
X+8=-2
x= -2-8 (you should make x the subject so you switch the +8 to the other
x= -10 side which becomes -8)
so you get -10 because, if both the numbers have the minus sign then you should add the two values which will be a negative answer. So your answer is option D
Answer:
Step-by-step explanation:
p = 106
L = 8 + 4W
p = 2L + 2W
p = 2(8 + 4W) + 2W
p = 16 + 8W + 2 W
p = 16 + 10W
106 = 16 + 10W
106 - 16 = 10W
90 = 10W
90/10 = W
9 = W
<h2>W = 9</h2><h2 />
L = 8 + 4W
L = 8 + 4(9)
L = 8 + 36
<h2>L = 44</h2>
44 + 44 + 9 + 9 = 106
44 * 9 = Area = 396
