A rectangle has a length of 4x plus 5 and a width of 8x minus 4. Which expression shows the perimeter of that rectangle? A: 4x +
mezya [45]

Answer: The answer is (D) 24x+2.


Step-by-step explanation:  Given that there is a rectangle, where length of the rectangle is given by

\ell=4x+5,

and width of the rectangle is given by

b=8x-4.

We are to find the perimeter of the rectangle. To do so, we need to add two times length with two times breadth of the rectangle.

Therefore, perimeter is given by

p=2\ell+2b=2\times(4x+5)+2\times(8x-1)=8x+10+16x-8=24x+2.

Thus, the correct option is (D).

Reason Abstractly Find two integers whose sum is -7 and whose
Travka [436]

Step-by-step explanation:

Let's represent the two integers with the variables x and y.

From the problem statement, we can create the following two equations:

x + y = -7

xy = 12

With the first equation, we can subtract y from both sides to isolate the x variable to the left-hand side:

x = -7 - y

Now that we have a value for x, we can plug it into the second equation and solve for y:

(-7 - y)y = 12

-7y - y^{2} = 12

Now, let's move everything to one side of the equation:

y^{2} + 7y + 12 = 0

Factoring this quadratic will give us two values for y:

(y + 4)(y + 3) = 0

y = -3, -4

Since we now know y = -3, -4, we can plug this back into either of the original equations to get a value for x, which will be x = -4, -3.

So the two numbers that sum to -7 and have a product of 12 are -3, -4.
