Answer:
x = 2
Step-by-step explanation:
- 2 + 2x = - x + 2 + x
2x + x - x = 2 + 2
2x = 4
x = 4/2
x = 2
Answer:
2 option= 3+3+3+3= 3(4) because it do not have exponent!!
Step-by-step explanation:
a)
the sum of the interior angles of a quadrilateral is 360°
so..
3x + 2x + x + 90 = 360
to find x..
3x + 2x + x + 90 = 360
3x + 2x + x = 360 - 90
6x = 270
x = 270/6
x = 45..
so x = 45
Find gradient by changing form of equation: y = 2/3x + 4. Gradient is 2/3.
Find y intercept of other line by substituting the coordinates: -8/3
Use information to write out equation of line: y= 2/3x - 8/3
Convert to standard form: -2x + 3y = 8.
Hope this helps :)
