Answer:
The responses to these question can be defined as follows:
Step-by-step explanation:
For point a:
For point b:
In order to solve this let us for at assume that the value of the width is X. Therefore the length will be x+5.
We can now write an equation:
(X+5) + (X+5) + X + X = 58
Combining like terms we should get
4X + 10 = 58
Now subtract 10 from both sides to get
4x = 48
Divide by 4 now and you should get
X = 12
Now we know the value of X and therefore the width.
Answer:
x=-19/2
Step-by-step explanation:
3(x+6)+6x+9=7x+8
3x+18+6x+9=7x+8
9x+27=7x+8
9x+27-7x=8
2x+27=8
2x=8-27
2x=-19
x=-19/2
Answer:
The diagonals of a square intersect cross in a 90 degree angle. This means that the diagonals of a square are perpendicular. The diagonals of a square are the same length congruent.
Step-by-step explanation:
so the answer is perpendicular
