Answer:
Step-by-step explanation:
3b⁵ + 15b⁴ - 18b⁷ = 3b⁵ + [3*5*b⁴] - [6*3*b⁷]
=3b⁴*( b + 5 - 6b³)
The square would be 100.
The semicircle you will use the formula πr^2/2.
That would mean you would take the 3.14x5^2/2.
(3.14x5x5)/2
(3.14x25)/2
78.5/2
=39.25
So the total area would be 139.25
Step-by-step explanation:
11/12-?=2/3
11/12-2/3=?
11-8/12=?
3/12
=1/4
Let us do it by converting the 0.4 to a fraction, it has one decimal, so we'll use one zero at the denominator.
and 9.21 to a fraction as well, two decimals, thus two zeros at the denominator then,
Y=3.5x
Pts are (1,3.5),(2,7),(3,10.5)
