#1 w=9 because:
2w+2(2w+3)=60
2*2w=4w and 2*3=6
2w+4w+6=60
Then: 2w+4w= 6w
6w+6=60
I just tried each answer I knew it had to be 8 or 9
So I tried 8 and it didnt work then I tried 9 and it did
6*9= 54+6=60
w=9
#2 I have a picture for this one I worked it out on paper. Check out the photo for the answer :)
Hope this helps!
Answer:
40000ftMSL
Step-by-step explanation:
We know that airspeed is measured using a pilot tube
And the air pressure is a function of density given as
Pressure= 1/2 xdensityx V²
So at 40,000ftMSL
Is this is replaced for V in the equation then the density of air will be 1/4 that of sea level
So since we are deriving velocity from pressure and pressure is 1/4 so the velocity Will be half of its pressure since velocity is squared from The equation above
Answer:
2x+73+56x31
Step-by-step explanation:
correct me
Remember that the rule with multiplying exponents with the same base is to add the exponents together.
In this case: 
10^12 is your answer.
Answer:
433 in.²
Step-by-step explanation:
Divide the figure into 2 rectangles
Area of the figure = area of the bigger rectangle + area of smaller rectangle
✔️Area of bigger rectangle = L*W
L = 29 in.
W = 13 in.
Area of the bigger rectangle = 29*13
= 377 in.²
✔️Area of the smaller rectangle = L*W
L = 7 in.
W = 8 in.
Area of the bigger rectangle = 7*8
= 56 in.²
✅Area of the figure = 377 + 56 = 433 in.²
