The answer is 10.
Parallel lines show similar triangles showing us that (2x + 6)/10 = (x+6)/8. Solving this equation for x gives us x = 2. Plugging this into 2x + 6 gives us 2(2) + 6 = 10.
1. 0.87 is the same as 87/100
87/100
Answer:
(6, -4)
Step-by-step explanation:
If ABCD is dilated by a factor of 2, you multiply the coordinates by 2. For the coordinate D', you would multiply 3 by 2 to get 6 and you would multiply -2 by 2 to get -4. Answer: (6, -4)
Yes. If you're given a lower triangle matrix A, then A = LU if L = A and U = I (the identity matrix). If your matrix is upper triangular, then A = LU with L = I and U = A.
Answer:
-7a^2 b^3
Step-by-step explanation:
-7(- a^2 )( -b^3 )
-7 * -a^2
A negative times a negative is a positive
7a^2
7a^2 * -b^3
A positive times a negative is a negative
-7a^2 b^3
