Answer:
a. (x+19)(x+1)
b. (z-1)(z-1)
c. 3(2x-3)
Step-by-step explanation:
a. x^2+20x+19
(x+19)(x+1)
b. z^2-2z+1
(z-1)(z-1)
c. 9(x-1)-3x
9x-9-3x
6x-9
3(2x-3)
C=2pir
area=pir^2
given
c=25.12
25.12=2pir
pi=3.14
25.12=2(3.14)r
25.12=6.28r
divide both sides by 6.25
4=r
sub into other
area=pir^2
area=pi4^2
area=16pi
area=16(3.14)
area=50.24
the area is 50.24 square cm
The answer would be 413,000,000 and 4,000
Ok so when you add fractions, the denominators have to be the same, therefore: (whole numbers you can still add)
5(1/2)+5(1/2)= 10(2/2), which equals to 11.
5(1/2) is also 5.5, since 1/2 is 50/100.
5.5 + 5.5 = 11
