Answer:
no
Step-by-step explanation:
1. to make up the equations of lines PQ and RS:
(PQ)
(RS)
2. to write the pointed verctors of PQ and RS:
for PQ it is p=(2;1); for RS it is r=(-2;1).
3. according to the pointed vectors it is clear, the given lines are not perpendicular <u>[2*(-2)+1*1≠0]</u>.

Answer:
the answer is X<3
Step-by-step explanation:
The area of a triangle is 1/2 bh
so to find the area of the larger triangle do the following calculation:
1/2 time 12 time 7. that will give you 42 ft squared. that is the larger triangle.
the next way to find the area i will show you is:
pretend that the the triangle is inside of a rectangle. now you have 4 triangles. you know that the base of the rectangle is 15 ft anf the height is 7. now take the smaller triangle and it has its rectangle base 3 and height 7. multiply to get 21 feet squared. divide by 2 since there are 2 triangles in the small rectangle. 10.5 feet squared
To be equal to 1, both the numerator and denominator need to be the same.
12/12 would be equal to 1.
