Answer:
9 ft, 28 ft, 26 ft
Step-by-step explanation:
The perimeter is the sum of side lengths, so ...
P = a + b + c
63 = n +(4n -8) +(2n +8) . . . . fill in the given side lengths
63 = 7n . . . . . . simplify
9 = n . . . . . . . . divide by 7
4n -8 = 36 -8 = 28 . . . . second side length
2n +8 = 18 +8 = 26 . . . . third side length
The side lengths are 9 ft, 28 ft, 26 ft..
To answer this, you use the formula 
where
is the simple interest that builds
is the principal (AKA the amount invested/borrowed)
is the interest rate per year
is the lenght of the loan, in years.
In your situation:
![\begin{aligned}I &= (\$3000)(5 \%/\text{year})(3 \text{ years})\\[0.5em]&= (3000)(0.05)(3)\\[0.5em]&= 450\end{aligned}](https://tex.z-dn.net/?f=%5Cbegin%7Baligned%7DI%20%26%3D%20%28%5C%243000%29%285%20%5C%25%2F%5Ctext%7Byear%7D%29%283%20%5Ctext%7B%20years%7D%29%5C%5C%5B0.5em%5D%26%3D%20%283000%29%280.05%29%283%29%5C%5C%5B0.5em%5D%26%3D%20450%5Cend%7Baligned%7D)
This means there'd be $450 of simple interest due at the end of 3 years.
Answer:
D
Step-by-step explanation:
It is the law of cos
C^2= A^2+B^2-2*A*B*cosL where L is the angle between A and B
so C = 32^2 + 35^2 - 2(32)(35)cos120°
Answer:
74mm
Step-by-step explanation:
296 divided by 4 sides is 74 mm each side
