Answer:

Step-by-step explanation:
The complete question is shown in the attachment.
The length of the rectangle is x + 12. The width of the rectangle is x + 3.
Recall that area of a rectangle is 
In terms of x, the area is 
Recall the distributive property of real numbers: 
We apply this property to get:

We expand again to get:

We now simplify to obtain:

The area of the rectangle is 
Answer:
-11/2
Step-by-step explanation:
<span>(-2x)/3 divided by 1/3?
Since you are dividing by a fraction, take that fraction, invert it and then multiply:
-2x 3
----- * ----- = -2x (answer)
3 1</span>
Answer:
not equivalent
Step-by-step explanation:
Given
= 
If the ratios are equivalent then ib cross- multiplying the 2 sides should be equal, that is
6 × 9 should equal 7 × 7
However, 54 ≠ 49
Thus the ratios are not equivalent
Given:
The quadratic equation is:

To find:
The solution for the given equation rounded to 2 decimal places.
Solution:
Quadratic formula: If a quadratic equation is
, then:

We have,

Here,
. Using the quadratic formula, we get




Now,



And



Therefore, the required solutions are 1.14 and -1.47.
