WebSee a solution process below: Explanation: Step 1) Solve the first equation for a : a+ 3b = 7 a+3b −(3b) = 7−(3b) ... Let us assume that p = 2a+ b+ c− prime. Then a2 − bc = a2 −b(p−2a −b) = (a +b)2 −pb. If this number is equal to n2, it is less a2, and n < a. It turns out that pb = (a +b +n)(a+ b− n), where both ... WebWe have to find the determinant of matrix 2A We have 2A=2×[1324]=[2648] Therefore the value of ∣2A∣= ∣∣∣∣∣∣2648∣∣∣∣∣∣=2×8−6×4=16−24=−8 Hence, ∣2A∣=−8. Video Explanation …

3.1 If A and B are two given matrices, find 2A-3B - YouTube

WebOct 28, 2024 · Your solution is correct except for a small problem. Note that when you cancelled $\sin (\alpha)$ from both sides you have to make sure to add the solutions of $\sin (\alpha)=0$ as well.. Also, you could have used the identity, $$2\cos ^2 (\alpha ) = 1+ \cos (2\alpha)$$ to have a shorter proof, but what you did in just fine. WebSolution: First of all, we’ll find the scalar multiples of the given matrix. The determinants: det (A) = 45. det (2A) = 360 = (8) (45) = 23det (A) Hence the property is verified.

For example, given two matrices A and B, where A is a m x p matrix and B is a p x n matrix, you can multiply them together to get a new m x n matrix C, where each element of C is the dot product of a row in A and a column in B. hansecatch hamburg
