Answer:
Bell Curve
Step-by-step explanation:
You cant factor by 9 because 15 cant be factored by 9. you can factor it by 5 and get 18x - 3 might want to check my answer
Answer:
its the first question i think it might be wrong idk
Step-by-step explanation:
because when you find the area you multiply two sides so you have to add 10 and 5 and then multiply it by 18
Base=9
Height=10
A=90
I think
Answer:
The area is 13,3 squared meters
Step-by-step explanation:
The 400 meters of fencing is the perimeter of the area. We know that:
perimeter = 2 (length + width)
or
P = 2 (l+w)
We also know that the length is twice the width, hence:
l = 2w
Substituting this information in the perimeter equation:
P = 2 (2w + w)
P = 4w+2w
P = 6w
w = P/6
Now, the area is defined as:
A = l*w
Therefore,
A = 2*w*w
A = 2 * w^2
Putting the w =P/6 in the previous equation
A = 2 * (P/6)^2
A = 2 * P^2/36
A = P^2/12
And substituting the value of P and doing the math,
A = 13, 333 period 3 which we need to round to 13,3 which is the total number of significant digits given
