We should follow the order of operations to solve this problem
7+18/(6-3)
First, we solve the problem in the parenthesis 6-3=3
7+18/3
Then we divide 18 by 3 which you get 6
7+6
Then you just add the remaining 7+6=13

Bananabusyo is correct. First we have to do the parentheses. 6-3 is 3. Then we have to divide 18 by 3 to get six. 7+6 = 13.

What factors multiply to -80 and add to 6
forsale [732]

80 = -1(80), -2(40), -4(20), -5(4),

Total answers include: -81, 79, -42, 16, -9, and 1.

None of them add up to 6!

Are you doing polynomial equations?

If so, you can solve it the hard way.

x^2 + 6x -80 = 0

(x^2 + 6x + 9) - 80 = 9

(x+3)^2 = 89

(x+3) = 9.43

x = 6.43

If you're not doing those then I'm afraid your question has no answer.

Hope that helps!

How much material is used
Neko [114]
This question is essentially asking you to find the surface area of the box.
The formula for SA on a rectangular prism is: 2(L*W+L*H+W*H)
L=Length W=Width H=Height

Lets input the information we know:
2(20*8+20*30+8*30)
Follow BEDMAS
2(160+600+240)
2(760+240)
2(1000)
2*1000
=2000

The box will need 2000 centimeters squared of material.

Hope this helps!

The final answer would be 39/19 it doesn't simplify any more and if it did the 19 would be reduced as well as the 39
