Answer:
Perimeter of rectangle = 4x + 80
Area = x² + 40x + 384
Step-by-step explanation:
Perimeter of rectangle = 2*(length + width)
= 2* (x + 24 + x + 16)
= 2*( x +x + 24 + 16) {Combine like terms}
= 2* (2x + 40)
Use Distributive property : a*(b +c) = a *b + a*c
= 2*2x + 2*40
= 4x + 80
Area of rectangle = length * width
= (x + 24) (x + 16) {use FOIL method}
= x*x + x*16 + 24*x + 24*16
= x² + 16x + 24x + 384 {Combine like terms}
= x² + 40x + 384
Answer:
Step-by-step explanation:
Complementary angles form a right angle and supplementary angles form a straight angle.
<h3>#7</h3>
<u>Complementary:</u>
<h3>#8</h3>
<u>Supplementary:</u>
- 2x + 6x + 20 = 180
- 8x = 160
- x = 20
Part 1
Kevin did not indicate the conversions between years, days, hours, and minutes.
Part 2
The correct calculation for the number of minutes in 2 years is
![2 \, years \\ = (2 \, years)*(365 \, \frac{days}{year})*(24 \, \frac{hours}{day} )*(60 \, \frac{minutes}{hour} ) \\ = 1,051,200 \, minutes](https://tex.z-dn.net/?f=2%20%5C%2C%20years%20%5C%5C%20%3D%20%282%20%5C%2C%20years%29%2A%28365%20%5C%2C%20%20%5Cfrac%7Bdays%7D%7Byear%7D%29%2A%2824%20%5C%2C%20%20%5Cfrac%7Bhours%7D%7Bday%7D%20%29%2A%2860%20%5C%2C%20%20%5Cfrac%7Bminutes%7D%7Bhour%7D%20%29%20%5C%5C%20%3D%20%201%2C051%2C200%20%5C%2C%20minutes)
