What is the length of the missing side of the quadrilateral shown if the perimeter is 5x^2+2x+1?
Answers
I am thinking that the quadrilateral is not given to be a rhombus.
The perimeter is the sum of the 4 sides.
Adding 2x^2 + x -1 to 3x^2 -5x and then that sum to 4x^2 gives
9x^2 - 4x - 1 as the sum of the three given sides.
Subtract that from the given perimeter to get the missing side length.
5x^2 + 2x + 1 - (9x^2 -4x -1) =
-4x^2 + 6x + 2

Step-by-step explanation:
x-intercept if when y is 0, so, on the x-axis. as we can see the x-intercept is -40
y-intercept if when x is 0, so, on the y-axis. as we can see the y-intercept is 15
Answer:
x-intercept:
y-intercept:
Step-by-step explanation:
The x-intercept is the point where the line meets the x-axis, and the y-intercept is the point on the line which meets the y-axis.
The line intersects the y-axis at , so the y-intercept is
.
The line intersects the x-axis at , so the x-intercept is
.

They're congruent, so pick one to work with, and discard the other one
temporarily.
In the right triangle:
-- The length of one leg is 'x'.
-- The length of the other leg is (2x + 7).
-- The length of the hypotenuse is 35.47 inches.
You know that in any right triangle:
(The square of the hypotenuse) =
(the square of one leg) + (the square of the other one.)
so you can use that to find the value of 'x'.
One you know the value of 'x', go back to the whole sign before you cut it
in half, and notice that the height of the sign is '2x' ... which is the answer.
if we cut the triangle in half from with the line from left to right, we have a trianlgle that is x high and 2x+7 wide and the hyposonuse that is 35.47 so
a^2+b^2=c^2
x^2+(2x+7)^2=35.47^2
x^2+4x^2+28x+49=1258.12
group like terms
5x^2+28x+49=1258.12
subtract 1258.12 from both sides
5x^2+28x-1209.12=0
factor 5(x-13.0008)(x+18.6008)=0
therefore
(x-13.0008) or/and (x+18.6008)=0
x-13.0008=0
add 13.0008 to both sides
x=13.0008
x+18.6008=0
subtract 18.6008 from both sides
x=-18.6008
since heights cannot be negative, this solution can be discarded
so x=13.0008
2x=height=26.0016

First, to find the boundary we need to find the amount of money left, simply subtract the spent amount from the total:
60 - 45.95 = 14.05
Seeing as this is the amount, she can spend any amount up to and including 14.05, so we need an equal to or smaller than sign:
Let x be the value of the object:
Which is the inequality!
