Answer:

-9

Step-by-step explanation:

In synthetic division we are multiplying the number -1 with the number written at the last line.

So here first we multiplied -1 with 3 to get -3, write it down below -4.

Now when we add -4 and -3 we get -7.

Again we multiply -1 with -7 , to get 7, writing it down below 2.

Then we add 2 and 7 to get 9.

Again we multiply -1 with 9 , that will give us -9.

So we write -9 below -1 in last column to get -10.

So the missing number is -9.

Le help needed with like terms and distributive property
Rashid [163]
Like terms would be taking all of the ones with a and getting them alone, all of the ones with b alone, and all plain numbers alone to simplify

1) 2a+3-5a+8b
****= -3a+8b+3****
take 2a-5a and that is your answer

2) 6a+rs-4a+6rs
=2a+rs+6rs
combine the a's 6a-4a
****=2a+7rs****
1rs+6rs combine rs's and that's it :)

**** is the answers

An open-topped glass aquarium with a square base is designed to hold 444 cubic feet of water. What is the minimum exterior surfa
In-s [12.5K]

Answer:

291.05ft²

Step-by-step explanation:

Volume of the aquarium = L³

L is the length of one side of the aquarium

444 = L³

L = cuberoot[444]

L= 7.63ft

Since the glass aquarium is opened at the top

Total surface Area = 5L²

Total surface Area = 5(7.63)²

Total surface Area = 291.05ft²

Hence the minimum exterior surface area of the aquarium is 291.05ft²

Find the equation of the line passing
Paraphin [41]
Rearrange the formula given to determine the slope, you will see that in y=mx+b form the slope is -2/3
You now have the slope (m) and two test points. Input those values into y=mx+b and you will have your answer!
I got y=(-2/3)x+(22/3) which I'm quite certain is correct.

(e) 0.892\div0.008

Step-by-step explanation:

Given

892\div8

Required

Select equivalent expression

8920\div80

894\div10

89.2\div0.08

8.92\div0.8

0.892\div0.008

Start  by solving the given expression (using a calculator)

892\div8 = 111.5

Then we solve the given options (using a calculator)

(a) 8920\div80

8920\div80 = 111.5

(b) 894\div10

894\div10 = 89.4

(c) 89.2\div0.08

89.2\div0.08 = 1115

(d) 8.92\div0.8

8.92\div0.8 = 11.15

(e) 0.892\div0.008

0.892\div0.008 = 111.5

The equivalent expressions are (a) and (e)
