Direction vector of line of intersection of two planes is the cross product of the normal vectors of the planes, namely
p1: x+y+z=2
p2: x+7y+7z=2
and the corresponding normal vectors are: (equiv. to coeff. of the plane)
n1:<1,1,1>
n2:<1,7,7>
The cross product n1 x n2
vl=
i j l
1 1 1
1 7 7
=<7-7, 1-7, 7-1>
=<0,-6,6>
Simplify by reducing length by a factor of 6
vl=<0,-1,1>
By observing the equations of the two planes, we see that (2,0,0) is a point on the intersection, because this points satisfies both plane equations.
Thus the parametric equation of the line is
L: (2,0,0)+t(0,-1,1)
or
L: x=2, y=-t, z=t
A square has four equal sides, four vertices, and is a closed, two-dimensional object. It has parallel sides on either side. A square is also equivalent to a rectangle with equal length and width. The square number will be

<h3>What is a square?</h3>
A square is a common polygon with four equal sides and angles that are each 90 degrees in length.
A square has four equal sides, four vertices, and is a closed, two-dimensional object. It has parallel sides on either side. A square is also equivalent to a rectangle with equal length and width.
Many objects can be found in your surroundings that have a square shape. The chessboard, craft sheets, bread slice, picture frame, pizza box, wall clock, etc. are typical instances of this shape.
Specifications of a Square
It has four vertices and four sides.It has equal-length sides.Since all interior angles are equal and right angles, they are all 90° in length.360° is the total of all interior angles.Its two diagonals form a straight angle with one another.

Well, since half is when you divide something by 2, divide 30 by 2
Then, you get 15
So Kristen made 15 sundaes!

1/6 is greater than 1/8, because when you change the fractions 1/6 will be 4/24 but 1/8 will be 3/24. To change the fractions you first have to find the lowest number that both denominators can go in, so it is 24. 6 can go into 24 four times, so you multiply the numerator by 4 making 1/6 4/24. 8 can go into 24 three times, so you multiply the numerator by 3 so 1/8 = 3/24.
Answer:
1/4 x 3 or 1/4+1/4+1/4
Step-by-step explanation:
1/4 + 1/4 + 1/4
2/4+1/4
3/4
