x = (a - 2x)/6z
a = 2x + 6xz
-2x -2x
a - 2x = 6xz
/6z /6z
(a - 2x)/6z = x
V = <span>πr^2h
V = </span><span>π . 6^2 . 11
V = </span><span>π . 36 .11
V = 396</span><span>π
if you use </span><span>π = 3.14 then
V = 396 x 3.14 = 1243.44
answer: </span>396π or 1243.44
Answer: 60° angle
Step-by-step explanation: AGD is a 90° angle, therefore, subtracting 30 from the 90 degrees gives you 60. As x is vertical to the 60 degree angle and verticals have the same degree measurement, x=60°.
Answer:
c. 9 det A
Step-by-step explanation:
Given the following data;
Since A is a square matrix of order 2, we know that n = 2
K = 3
For any scalar k;
∣kA∣ = k^{n} ∣A∣
<em>Substituting into the equation;</em>
∣-3A∣ = -3²∣A∣
Simplifying, we have;
∣-3A∣ = 9∣A∣
= 9 detA
<em>Therefore, det (-3A) = 9 detA</em>
