Answer:
Supposing that every squre is 1cm^2 large
- The rectangle A has an area of 32cm^2
- The rectangle B has an area of 20cm^2
Total area: 52cm^2
Step-by-step explanation:
Rectangle area formula is B*H
(I made it in cm^2 'cause I'm from Europe)
5(x+4)=-15
Distribute
5x+20=-15
Subtract 20 from both sides
5x=-35
Divide both sides by 5
x=-7
Final answer: The number is -7

Answer: A. 21</h3>
=======================================
C(n, r) = (n!)/(r!*(n-r)!) is the combination formula
C(7, 5) = (7!)/(5!*(7-5)!)
C(7, 5) = (7!)/(5!*2!)
C(7, 5) = (7*6*5!)/(5!*2!)
C(7, 5) = (7*6)/(2!) ..... note the "5!" terms divided and canceled
C(7, 5) = (7*6)/(2*1)
C(7, 5) = 42/2
C(7, 5) = 21
Answer: p = 42
The bottom chord is 21+21 = 42 units long. This bottom chord is 11.2 units away from the center. Any other chord the same distance from the center will have the same length. The top chord has the same length of 42 units as it is also 11.2 units from the center.
