We conclude that:

Hence, option B is correct.
Step-by-step explanation:
Given the expression

solving

Scalar Multiplication: Multiply each of the matrix elements by a scalar

Simplify each element

Therefore, we conclude that:

Hence, option B is correct.
Answer:
35
Step-by-step explanation:
IF the middle is 18 then there aer 17 infront and 17 in back added together equals 35.
29) First of all when I write “^2” I mean to the power of 2. Label the bottom line Z or whatever u fancy. Then make 3 equations to solve simultaneously using a^2+b^2=c^2
(1) 14^2+y^2=Z^2
(2) 6^2+y^2=x^2 and (3) x^2+z^2=20^2
The next step is to solve them simultaneously e.g you can rearrange (2) to give you y^2=x^2-6^2 and then input that into (1) to get 14^2+x^2-6^2=Z^2 and again you rearrange (3) to get z^2=20^2-x^2 and input that in and solve for x. Then you will have to repeat that solving for y and only y as the question doesn’t originally ask for z but only for the values of x and y I assume. Using this idea, from glancing at the other questions you should be able to apply this concept to those other questions, if not then make another post outlining any specific questions
Just multiply straight across. (Left to right.)
Multiply both numbers on the top then both on the bottom. Then just simplify.
An example is 1/2 x 3/4 = 3/6 then 1/2
Answer:
S8 = 112
Step-by-step explanation:.
The question is incomplete
Assuming we are given the following
First term a =7
number of terms n = 8.
Common difference d=2
We can find the sum of the first 8terms S8
Substitute the given values
S8 = 8/2[2(7)+(8-1)(2)]
S8 =4(14+7(2))
S8=4(14+14)
S8 = 4(28)
S8 = 112
Hence the sum of the first 8terms is 112
Note that the values are assumed values
