I would say technician B is probably right when talking about a construction sight. Construction sights could be worked on in storms, near power lines, or be near power sources when doing their job. It’s also heavy so in case there is wind or something when they are attempting to scale a building, it’s not as dangerous as the aluminum.

Find the sum of the first 36 terms of the following series, to the nearest integer.<br> 2, 5,8,...
Ivenika [448]

Answer:

Step-by-step explanation:

Comment.

You need to use the addition formula when the last term is not given. Mind you, you could find it, but it is just as easy to get the answer without it.

Givens

a1 = 2

d = 3

n = 36

Formula

Sum = n(a1 + (n - 1)* d)/2

Solution

Sum  =  36(2 + (36 - 1)*3 )/2                Combine the brackets

Sum = 36 (2 + 35*3 )/2

Sum = 36(2 + 105) /2                          Combine the brackets

Sum = 36 * 107/2                                    

Sum = 3852 /2

Sum = 1926

Answer

1926

STALIN [3.7K]

Answer:

-5x^3 -10x^2

Step-by-step explanation:

(x^2 *(x+2))(-5)

(x^2 x + x^2*2)(-5)

Multiply x^2 by x by adding exponents

(x^3+x^2 *2)(-5)

Apply the distributive property

(x^3 + 2x^2)(-5)
