Answer:
be specific
Step-by-step explanation:
which shaded eing
Step-by-step explanation:
if the 2 matrices are inverse, then their product must be the identity matrix
1 0
0 1
so,
m×3 + 2×-7 = 1
7×3 + 3×-7 = 0
m×-2 + 2×m = 0
7×-2 + 3×m = 1
that means we have to solve only
3m - 14 = 1
3m = 15
m = 5
4:2 because it goes cars then buses
Answer:
1. List the prime factors of each number
2. Multiply those factors both factors have in common. If there are no common prime factors the GCF is 1.
Step-by-step explanation:
Use the factor tree method
Answer:
50, 48, 14
Step-by-step explanation:
Go through them one by one. The side lengths of a triangle should all plug in to the formula a^2 + b^2 = c^2. The longest side is always c because it is the hypotenuse. The other two sides are interchangeable.
8^2+ 14^2 should equal 17^2.
That simplifies to
64+196=289
That can't be true because the units digits add to 10 instead of 9.
The same method applies to 3, 5, and 6 but from experience I know that this already isn't an option.
For 50, 48, and 14, you can divide everything by 2, resulting in 25, 24, and 7.
576+49 should equal 625.
That is true.
For 53, 48, and 24
576+2304 should equal 2809.
That isn't true, it equals 2880.
