-2(x+14)+1=15
distribute
-2x - 14 + 1 = 15
add 14 to each side
-2x + 1 = 29
subtract one from each side
-2x = 28
divided by -2
x = -14
Please upload a picture of the kite.
The frame will go around all 4 sides of the painting. That means that the length of each side of the painting will increase by 2.5 inches. The height, <em>h</em>, will now be <em>h</em> + 5 (2.5 inches on the top and the bottom). The width, 2<em>h</em> + 3, will now be 2<em>h</em> + 3 + 5 (again, 2.5 inches on the top and the bottom). The area would be given by
(<em>h</em> + 5)(2<em>h</em> + 3 + 5) = (<em>h</em> + 5)(2<em>h</em> + 8)
Multiplying this, we have:
<em>h</em>*2<em>h</em> + <em /><em>h</em>*8 + <em />5*2<em>h</em> + 5*8 = 2<em>h</em>² + 8<em>h</em> + 10<em>h</em> + 40 = 2<em>h</em>² + 18<em>h</em>² + 40

Answer:
hypotenuse is 22.47 m
Step-by-step explanation:
The length of both legs of a right angle triangle are 8m and 21 m
We need to find the hypotenuse
To find hypotenuse we use Pythagorean theorem
Hypotenuse is AC and other two legs are AB and BC
Hypotenuse ^2 = 8^2 + 21^2
hypotenuse =
=
=
= 22.47
So the length of the hypotenuse is 22.47 m
