Answer: A quadrilateral has vertices A(3, 5), B(2, 0), C(7, 0), and D(8, 5). Find:

You can see that vectors and This means that opposite sides are parallel and option B is false.

Find the lengths of all sides:

As you can see the lengths of opposite sides are equal, but all lengths are not equal. Therefore, the last option D is false.

Now check whether angles A and B are perpendicular:

The dot products are not equal to zero, then angles A and B are nor right. This means that option C is false and option A is correct (ABCD is a parallelogram with non-perpendicular adjacent sides

AKA your correct awnser choice is A :)✨

The solution to given system of equations are x = -1, y = 1 and z = 5 which is determined by the substitution method.

The given system of equations below as

4x – 2y + 3z = 9  ....(i)

x - 2y = -3             ....(ii)

2x + 3y = 1            ....(iii)

By equation (ii) and solving for x to get

x - 2y = -3

x = 2y - 3    ....(iv)

Substitute the value of x = 2y - 3 in the equation (iii)

2(2y - 3) + 3y = 1

4y - 6 + 3y = 1

7y = 7

y = 1

Substitute the value of y = 1 in equation (iv) to get,

x = 2(1) - 3

x = -1

Substitute the values of x = -1 and y = 1 in equation (i), and solve for z

4(-1) – 2(1) + 3z = 9

-4 - 2 + 3z = 9

3z = 15

z = 5

Therefore, the solution to given system of equation are x = -1, y = 1 and z = 5.

Answer:

x = 12

Step-by-step explanation:

The angle vertically opposite to ∠ 2 is corresponding to ∠ 1 and congruent, so

∠ 2 = ∠ 1 , substitute values

2(5x - 3) = 9x + 6 ← distribute parenthesis on left side

10x - 6 = 9x + 6 ( subtract 9x from both sides )

x - 6 = 6 ( add 6 to both sides )

x = 12

Width <= 5 and length <= 9

Step-by-step explanation:

Width: x

Length: x+4

2x + 2(x+4) <= 28 (less or equal)

2x + 2x + 8 <= 28

4x <= 28-8

x <= 20/4

x <= 5

If  length of a rectangle is 4 cm longer than the width the perimeter is no more than 28 cm. Then length of rectangle is lesser than or equal to 5 and width is lesser than or equal to 9.

The area of Rectangle is length times of width.

Let us consider width of rectangle be w= x cm

From given  length of a rectangle is 4 cm longer than the width

l=(x+4)cm

The perimeter of rectangle =2(Length+width)

=2(x+x+4)

=2(2x+4)

=4x+8

the perimeter is no more than 28 cm

4x+8≤28

Subtract 8 on both sides

4x≤20

Divide both sides by 4

x≤5

Hence  length of rectangle is lesser than or equal to 5 and width is lesser than or equal to 9.
