Answer:
15
Step-by-step explanation:
=> (-3)²+(-4+7)(2)
=> 9+(3)(2)
=> 9+6
=> 15

Answer:
Area of the rectangle is given by:
where
A is the area of the rectangle
l is the length of the rectangle
w is the width of the rectangle respectively.
As per the given statement:
Area of the rectangle(A) = 
square meters
length of the rectangle(l) = x+8
Substitute these in the given formula we have;
or
Divide both sides by x+8 we have;
meters.
Therefore, the expression represents the width of the rectangle is x-9 meters
Answer:
Y=s^2/36 and y=5.7;14.3 ft
Step-by-step explanation:
The question was not typed correctly. Here, a better version:
<em>The aspect ratio is used when calculating the aerodynamic efficiency of the wing of a plane for a standard wing area, the function A(s)=s^2/36 can be used to find the aspect ratio depending on the wingspan in feet. If one glider has an aspect ratio of 5.7, which system of equations and solution can be used to represent the wingspan of the glider? Round solution to the nearest tenth if necessary. </em>
<em>
</em>
<em>Y=s^2/36 and y=5.7;14.3 ft
</em>
<em>Y=5.7s^2 and y=36; s=2.5ft
</em>
<em>Y=36s^2 and y=0; s=0.4 ft
</em>
<em>Y=s^2/36 +5.7 and y=0; s=5.5 ft</em>
In the function A(s)=s^2/36 A(s) represents the aspect ratio and s the wingspan. If one glider has an aspect ratio of 5.7, then A(s) = 5.7. We want to know the wingspan of the glider. Replacing A(s) by Y we get the following system of equation:
Y=s^2/36
with y = 5.7
5.7 = s^2/36
5.7*36 = s^2
√205.2 = s
14.3 ft
It would be A, because her annual premium rate is $3.25 for every $1,000. So 3.25x130=$422.50
