The answer is 32. you would multiply 8 times 4 which is 32 feet.
Answer:
No
Step-by-step explanation:
If A were reversible, then such y coudnt not exist, because A⁻¹y would be a solution of the equation Ax=y. This means that A in not reversible, thus, there exist a non zero vector w in R³ such that A*w = 0. If x' were a solution of Ax =z, then x'' = x'+w is a different solution of the equation: Ax'' = A(x'+w) = Ax'+Aw = z+0 = z. This means that a vector z such that there exist a unique solution for the equation Ax=z cant exist.
Answer:
b =15
Step-by-step explanation:
The sum of the angles of a triangle is 180
5b+ 4b+ 3b = 180
12b = 180
Divide by 12
12b/12 =180/12
b =15
Answer: Look at the picture
Step-by-step explanation: Hope this help :D
An expression is a mat scentence but not a complet on.Example:2x3. Or a x 5. I hope I said it clearly for you.
