Answer:

$\Huge \boxed{20}$

Step-by-step explanation:

This question is about order of operations. It stands for parenthesis, exponent, multiply, divide, add, and subtract from left to right.

First thing you do is parenthesis.

$\displaystyle [2-6]=-4$

$\displaystyle -4-[-24]$

Then, add and subtract numbers from left to right to find the answer.

$\displaystyle -4-[-24]$

$\displaystyle -4-[-24]=-4+24=20$

20, which is our answer.

Hope this helps!

The length of a rectangle is 3 inches more than its width. the area of the rectangle is 40 square inches. what is the length, in

IceJOKER [234]

Since width is the smaller value, set width=x. That wold mean that length=x+3. Since Area=width*length, 40=x(3+x). Distribute the x to give you 40=3x+x^2. Set the equation equal to 0 giving you x^2+3x-40=0. Factor the equation to give you (x+8)(x-5)=0. Set each factor equal to 0. x+8=0 gives you x=-8 & x=-5 gives you x=5. Since we're working with lengths of objects, it can't be negative. Therefore, your width is 5. To find length, substitute width into the original expression (x+3). Therefore, length is 5+3=8.
