Answer:
The total route is 8 kilometers.
Step-by-step explanation:
Let the distance of the total route be x
Marta has gone for a walk and has covered three quarters of the total route so far. This means that she has covered a distance of
3/4 × x = 3x/4 kilometers
she still has 2 kilometres to walk. This means that the total route or distance = the sum of the distance that she covered already and the distance she has remaining. Therefore,
x = 3x/4 + 2
x - 3x/4 = 2
(4x - 3x) / 4 = 2
Cross multiplying
4x - 3x = 4 × 2
x = 8
The total route is 8 kilometers.
Answer:
B. y=0
Step-by-step explanation:
The length of the AC is x^2 + 4x - 12.
<h3>What is a parallelogram?</h3>
That quadrilateral in which opposite sides are parallel is called a parallelogram.
Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.
Given :
In Parallelogram ABCD, diagonals AC and BD intersect at point E.
such that
AE = x^2 - 12,
CE = 4x
We know that the diagonal of a parallelogram bisect each other.
x^2 - 12 = 4x
x^2 - 4x - 12= 0
(x-6)(x-2) = 0
Hence, the value of x = 6, 2.
AC = AE + CE = x^2 + 4x - 12.
The length of the AC is x^2 + 4x - 12.

Side Angle Side Postulate. The Side Angle Side postulate (often abbreviated as SAS) states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.
Answer:
32
Step-by-step explanation:
4 × 8 - 32
Hence, 32 is the required answer.
