Solve for x please describe the steps 50 points
LuckyWell [14K]

Answer:

x = 6

explanation:

USE: \boxed{\frac{side-length }{base -length} = \frac{side-length}{base -length} }

solve:

\frac{21}{15} = \frac{7}{x-1}

21(x-1) = 7(15)

21x-21 = 105

21x = 105+21

21x = 126

x = \frac{126}{21}

x = 6

Let S = {A, B, C, D} be some set of four elements of a vector space. Suppose that D = 2A + B + 3C and C = A − B. Is {A, B, D} li
Olin [163]

Answer:

As explained

Step-by-step explanation:

given that D = 2A + B + 3C and S = {A, B, C, D}, C = A − B

for {A, B, D}  to be linearly dependent implies that A B and D will have values that not dependent on the sample space C.

if C = A -B is substituted in the original equation, the generated equation, 5A -2B will have values each as against C which is linearly independent.

Also, D will have values that are linearly dependent.
