Combined usually means to add. You only add the top.
Answer:
Step-by-step explanation:
f(x) = –(x – 3)2 + 9
= 3² - (x – 3)2 identity a²-b² = (a+b)(a - b) where : a =3 and b = x-3
= ( 3+x-3) (3-x+3)
f(x) = x( 6-x)
the perimeter is ; 2(x +6-x) =12
the maximum area of the rectangle is : f(3) = 9 m²
25 divided by 23 will not come out as a whole number. 23 goes into 25 1 time so the answer would be 1..... But I guess the answer would be A since that's the closest answer choice.
Answer:
8.31
Step-by-step explanation:
Using the Pythagorean Theorem:
The side length for 
, rounded to the nearest hundredths, would be 8.31.
2.8a^2=55
a^2=55/2.8
a= square root of 55/2.8
