Answer:
x= -2
Step-by-step explanation:
7x+26+5x=2
7x+5x=12x
12x=2-26
12x= -24
(divide both sides by 12)
x= -2
This expression is a difference of squares:

Answer:
1 ) 180 - 71 = 109
2) 5x +x = 180 ; 6x = 180 ; x = 180/6 = 30
3) 90
4) x + 6x+8 + x+12 = 180 ; 8x + 20 = 180 ; 8x = 160/8= 30
5) 180 -110 = 70
6) m = 180- 119 = 61
7) 90
8) 11y - 36 = 63 ; y = 99/11 = 9

(Q7) 180
(Q8) 2x+x = 3x = 90 ; x = 90/3 = 30
(Q15) 157
(Q16) 5x + 4 + (x-2) + (3x+7) = 180
9x +9 = 180 ; x = 171 / 9 = 19
I hope im right!!
Answer:
y = 11
Step-by-step explanation:
Since our plane is parallel to the xz plane, the x and z are independent of each other, i.e. they could be anything. So xz plane has an equation of y = 0. So if this plane is located 11 units to the right of the xz plane then its equation must be y = 11.
