54 I believe because well you can break the shape up into some triangles and a square to find the area.
Answer:
5
Step-by-step explanation:
Let the number be x
Therefore 3times the number will be 3x
3x + 2= 17
3x =17-2
3x=15
x=15/3
x= 5
Step-by-step explanation:
To find the gradient:
y2-y1/x2-x1
Pick any two coordinates
11)
(4,3) and (1,-1)
-1-3= -4
1-4= -3
-4/-3 = 1.3(1dp)
12)
(0,1) and ( 2,-2)
-2-1= -3
2-0= 2
-3/2= -1.5
Might be wrong but this is what I got from what I have learnt.
Hope this helps! :)
If two line segments intersect at 90 degrees, then two line segments are perpendicular.
Answer:
x^2+4x-77
Step-by-step explanation:
distribute x+11 to x-7
x*x-x^2
x*-7=-7x
11*x=11x
11*-7=-77
combine like terms with -7x and 11x to get 4x
x^2+4x-77
