What is -5x-5(8x)=0 solve for x

2 answers:

7 0

Multiply -5 and 8x to get -40x
then subtract 40x from -5x to get -45x
lastly divide 0 by -45 to get 0
x=0
hope this helps :)

-45(x) = 0 {Solve this}
Now, lets multiply (×) by both sides of the problem
45{x} = 0
Divide each of the sides of the problems by the number 45
So, this means that the value of x is probably going to be 0 ; x = 0

Answer:

The dimensions are:

$3(2x+1)$ by $(7x+5)$

Step-by-step explanation:

The area of the rectangle is given as

$A=42x^2+51x+15$

The factored form of this quadratic trinomial gives the dimensions of the rectangle.

We factor 3 first to obtain;

$A=3(14x^2+17x+5)$

We split the middle term to get;

$A=3(14x^2+10x+7x+5)$

We factor within the parenthesis to get;

$A=3(2x(7x+5)+1(7x+5))$

We factor further to get;

$A=3(2x+1)(7x+5)$

The dimensions are:

$3(2x+1)$ by $(7x+5)$

Then the perimeter will be

$2(6x+3+7x+5)=26x+16\:\:\:\boxed{\sqrt{} }$

A NUMBER , TRIPLE THAT NUMBER , AND 12 ARE ADDED THE RESULT IS 32

liraira [26]

If you want to find out what that number is, then let's call it n
n + 3n (Three times the number) + 12 = 32
Simplify
4n + 12 = 32
Subtract 12 from each side
4n = 20
Divide each side by 4
n = 5

x = 17

Step-by-step explanation:

These angles are supplementary so (2x + 5) + (8x = 5) = 180 then you just do the algebra
