Simplest method: elimination.
Subtract the first equation from the second one.
(2a+b=-33)-(a+b=-10) gets you to a=-23.
Now plug that in for a and solve.
-23 +b=-10
b=13
So 9 Gallons a second is 2160 Quarts a minute
Your factored answer will be
(3x-4y) (x-5y)
hope this helps
Answer:
-14
Step-by-step explanation:
(-6)(2)= -12
(-8÷4)= -2
-12+(-2)= -14
The area of the regular heptagon which has a radius of approximately 27.87 cm and the length of each side is 24.18 cm is 2125 cm².
<h3>What is the area of a heptagon?</h3>
Heptagon is the closed shape polygon which has 7 sides and 7 interior angles.
The area of the regular heptagon is found out using the following formula.

Here, (<em>a</em>) is the length of the heptagon.
A regular heptagon has a radius of approximately 27.87 cm and the length of each side is 24.18 cm. Put the value of side in the above formula,

Hence, the area of the regular heptagon which has a radius of approximately 27.87 cm and the length of each side is 24.18 cm is 2125 cm².
