Answer:

x = -10

x = 7

Step-by-step explanation:

2(x+3) = x - 4

2x + 6 = x - 4

2x -x = - 4 - 6

x = - 10

4(5x-2) = 2(9x+3)

20x - 8 = 18x +6

20x - 18x = 6 + 8

2x = 14

x = 7

have a nice day :D

2x(x + 3)= x - 4
2x + 6 = x - 4
2x - x - 4
X = -10

4(5x + -2) = 2(9x + 3)
20x - 8 = 18x + 6
20x -18x = 6 + 8
2x/2 = 14\2
X = 7

4/5 x = 8 i need to show my work​
Anika [276]

Answer:

x=10

Step-by-step explanation:

I'm assuming you needed to solve for x. Here is how you do it:

first, divide both sides by 4/5 to get x by itself.

this will give you x=8 divided by 4/5.

To solve 8 divided by 4/5 you do keep switch flip.

keep the first number (8), switch the sign (division to multiplication), and flip the other fraction (4/5 to 5/4) then you can just multiply across the top (8/1 *5/4) which equals 40/4. This simplified is 10

Katniss divided x^3+2x^2-3x-4 by x+1. she didnt get a remainder. do you agree with her?
Brilliant_brown [7]

ANSWER

Katnis is right

EXPLANATION

We use the Remainder Theorem to check if she is right.

According to the Remainder Theorem, if the polynomial function,

p(x) =  {x}^{3}  + 2 {x}^{2}  - 3x - 4

is divided by x+1, then the remainder is given by

p( - 1)

We substitute x=-1 into the function to obtain,

p( - 1) =  {( - 1)}^{3}  + 2 { ( - 1)}^{2}  - 3( - 1) - 4

We simplify to get:

p( - 1) =  -  1+ 2 (1)   + 3 - 4

p( - 1) = 4- 4

p( - 1) = 0

Katnis is right because the remainder is zero
