3x2 + 10x − 8 = 0
4x2 + 10x − 2 = 0
x2 + 7x − 8 = 0
Represent the thickness of the frame by x. Framing the mirror will increase both its length and width by 2x. The area of the mirror with the frame is the product of the length and width which can mathematically be expressed as,
A = (3 + 2x)(2 +2x) = 8
The equation above can be simplified into 4x^2 + 10x -2 = 0. This equation can still be further simplified by dividing it by 2. However, it will give an answer which is not found on the choices. Thus, the answer is the third choice.
Answer: The answer above me is correct .
Answer:
y= -x+6
Step-by-step explanation:
The equation format for slope-intercept form is y=mx+c, where m is the slope of the line and c is the y-intercept.
To find the slope, we need to pick two definite points and find the slope from that. The formula to find the slope is 'rise/run'. Rise is the difference between the y-values of the two points, and the run is the difference between the x-values of the two points.
Let's use the points (0,6) and (1,5).
The rise is -1 (5-6=-1) and the run is also 1 (1-0=1). This means that the slope is -1 (-1/1=-1). The slope is negative because the line is 'going downwards'.
So our equation so far is:
y=-x+c
The y-intercept is where the line crosses the y-axis and the x-value is 0. We can see from the graph that the line crosses the y-axis at the point (0,6), therefore the y-intercept is 6.
So our final equation for the line is y= -x+6.
Hope this helped!
The the equation of the line is y= -x+6.
We have to make use the points (0,6) and (1,5).
We have a rise of -1 (5-6=-1)
We also have a run of 1 (1-0=1).
Now we have to find the slope
This is solved as the slope is -1 (-1/1=-1).
The slope is negative Given that we have a line that goes downwards
The y-intercept is where the line crosses the y-axis and the x-value is 0. We can see from the graph that the line crosses the y-axis at the point (0,6), therefore the y-intercept is 6.
Therefore the equation is y= -x+6.

The answer to the mathematical problem 6 times 2/3 is 4. This is solved by turning the whole number 6 into a fraction (6/1), multiplying the numerators together (6 times 2 equals 12), multiplying the denominators together (1 times 3 equals 3), and putting the new numerator over the new denominator (12/3), which simplifies to 4.
The question is asking you to multiply 6 by 2/3. Let's follow the steps to solve this multiplication problem.
So, 6 times 2/3 equals 4.

Answer:
b =
Step-by-step explanation:
The area of the parallelogram is represented by
The height is
The base of the parallelogram, b, can be found by dividing the area by the height.
So, 'b' can be found as
In simplified form, we can write this as :
=>
=>
Hence, base or 'b' is
If a quadrilateral is a parallelogram then opposite sides are parallel. For example, look at the diagram I provided below. If quadrilateral A,B,C,D is a parallelogram, then side A,B is parallel to side D,C. Also, side A,D must be parallel to side B,C.
Hey there! :D So you're wondering how you can tell if a quadrilateral is a parallelogram, right? Well, you are about to find out! The way you can tell whether a quadrilateral is a parallelogram because we know that a quadrilateral has 4 sides, right? And a parallelogram is a figure with opposite sides that never intersect or cross. So for example, a square is a quadrilateral and it has 4 equal sides and if we extend the lines horizontally, the would not cross.
I hope this makes sense to you! Have a good evening!(If you are in the US, but if you aren't, good morning!) :D
