Answer:
well 4/3 is 1 1/3 and also times pie and times 3
Step-by-step explanation:
<span>3a4-2a2+5a-10)-(2a4+4a2+5a-2)
remove first set of parentheses:
apply "-" sign to second parentheses (distributive prop):
the - of a - becomes a + :
combine like terms:
Factor out the variables that are alike:
{(1)a^4 + (-6)a^2 + 0a + (-8)}}}
0a is just 0, makea the "a" term go away:
can try to factor as squares, but it doesn't work out:
8 = (-4) x (+2) product factors cannot add to make 6. </span>
Answer:
r=5
Step-by-step explanation:
r+2=7
r=5
Area of a semi-circle = 1/2 x x r square.
area of larger semi circle
= 1/2 x x 10 square
= 50
area of smaller semi circle
= 1/2 x x 5 square
= 12.5
Total area = 50 + 12.5 = 196 cm square ( to 3 sf ) or 62.5
18 meters converted into centimeters is 1,800 centimeters
