Two consecutive odd number have the form: 2n+1; 2n+3.
We have:
(2n+1)(2n+3)=399
=> 4x^2+8x+3=399
=> 4x^2+8x-396=0
=> 4(x+11)(x-9)=0
=> x=-11; x=9
Answer:
A <em>plane</em> is a two-dimensional surface that can contain points, rays, and lines, including parallel lines.
Answer:
The coordinates would be A(6,2), B(7,6), C(3,5), D(2,1)
Step-by-step explanation:
When conducting a 180 degree rotation, you can just reverse the points to get your answer.
Answer:
B= 6
Step-by-step explanation:
pythagorean theorem formula is a² + b² = c²
so: 8² + b² = 10²
then: 64 + b² = 100
subtract 64 from both sides to get b²= 36
square root 36 and you get 6 for b
answer: B= 6
